This release note describes the features and caveats for Cisco 700 software Release 4.1(2) and earlier. For complete software documentation for Cisco 700 software, refer to the Cisco 700 Series Command Reference.
This document includes the following sections:
Cisco 700 series router software Release 4.1(2) supports the following routers:
Cisco 760 Series | Cisco 770 Series | CPA760 Series |
---|---|---|
Cisco 761 | Cisco 771 | CPA761 |
Cisco 762 | Cisco 772 | CPA762 |
Cisco 765 | Cisco 775 | CPA765 |
Cisco 766 | Cisco 776 | CPA766 |
The following documentation is provided with your Cisco 700 series router:
These are the enhancements for Cisco 700 series router software Release 4.1(2).
The callback delay value can be set by using the CLId Callback Delay command. In software Release 4.1(1), the callback delay was a fixed value (3 seconds). In some environments, a fixed value caused a problem when the callback collided with the incoming call attempt.
The caller ID number can be different from the called number in the profile. If the CLIValidatenumber parameter is specified in a profile, the router tries to match the caller ID number of the calling device with the CLIValidatenumber. If the numbers match, the router calls back to the calling device using the called number in the profile, or it uses the backup number if the first attempt to call using the called number failed.
If the CLIValidatenumber is not specified or the numbers do not match, the router tries to match the caller ID number from the calling device with the Called Number parameter in the profile. If the numbers match, the router calls back to the device using the called number, or it uses the backup number if the first attempt to call using the called number failed.
The CLIdAuthentication command allows the router to determine the profile to use for an incoming call by looking at the caller ID number. If the incoming caller ID number matches the caller ID validate parameter in the profile, incoming PPP authentication is disabled for the call and the profile is used for the connection. If no match is found in any of the profiles, the call is processed as determined by the current configuration.
The call transfer features prior to software Release 4.1(2) did not respond to standard procedures. The procedures have been replaced with industry-standard procedures.
Call transfer is the ability to transfer an active call to another number. The default feature activation code for call transfer is 61. (Some countries that use the NET3 switch do not support ISDN provisioning for call transfer.)
Take the following steps to transfer an active incoming call to another telephone number:
Step 1 Perform a hook switch flash (quickly press the telephone receiver button once) to get a dial tone.
If your analog telephone device offers the option, you can press the Flash key instead of the hook switch flash to put the call on hold.
Step 2 Dial the number to which the call is to be transferred.
Step 3 Hang up the receiver. The call is transferred.
If the transfer fails, the caller remains on hold and the telephone rings to alert you to the call on hold.
Three-way call conferencing adds another party to an active call. (Some countries that use the NET3 switch do not support ISDN provisioning for three-way call conferencing.) Up to three people can be connected using three-way conferencing. (For DMS and NI1, the default feature activation code for three-way call eonferencing is 60.)
Take the following steps to add a third party to an active call:
Step 1 Perform a hook switch flash (quickly press the telephone receiver button once) to get a dial tone. At the same time, the active call is placed on hold.
If your analog telephone device offers the option, you can press the Flash key instead of the hook switch flash to put the call on hold.
Step 2 Dial the second call.
Step 3 Perform a hook switch flash when the second call is answered to connect all the callers.
Call hold and retrieve is the ability to place a caller on hold, make a second call, and return to the first call. (Some countries that use the NET3 switch do not support ISDN provisioning for call hold and call retrieve.)
To place a call on hold:
Step 1 Perform a short on-hook (quickly press the telephone receiver button once) to get a dial tone.
If your analog telephone device offers the option, you can press the Flash key instead of the short on-hook to put the call on hold.
Step 2 Dial the hold access number, **95#.
Step 3 Dial the second call.
To retrieve the call placed on hold, perform the short on-hook or press the Flash key again.
If you have a call on hold and you hang up, the telephone rings, indicating a call is on hold. Picking up the telephone receiver connects you to the caller on hold.
Two parameters, demand and ignore, have been added to the set ip filter command. When demand is set, packets that match the filter are counted in the threshold values that keep the ISDN line connected or bring the ISDN line up if it is down. When ignore is set, packets matching the filter are not counted in the threshold values, and it will not bring the ISDN line up.
CHAP (Challenge Handshake Authentication Protocol) challenges sent to another device are specially coded. This security feature stops another device from gaining unauthorized access.
When the HTTP server is on, any user can use the Web browser application, ClickStart, to change the configuration of the router. To provide additional security, the set clickstart command turns off the HTTP server when the HTTP server is not in use.
A password contained in a configuration file can be downloaded through TFTP, making it possible to configure a Cisco 700 series router in one step. The commands for setting system, CHAP, and PAP passwords have been changed to allow passwords to be entered using the command line. In addition, the router accepts an encrypted password.
The version command status information has been expanded to indicate the amount of installed DRAM, the size of the installed Flash memory and the ROM version.
This section describes the known limitations of software Release 4.1(2). Each item includes the Cisco DDTS tracking number, if applicable.
For 5ESS Custom swiches, Cisco 700 series routers do not support multiple directory numbers. If a call is destined for a secondary directory number, the Called Party Number IE parameter contains the primary directory number. Therefore, the ring cadence (distinctive ringing) and routing of the phone call might not be accurate.
This section describes suggestions for optimum use of Cisco 700 series router software Release 4.1(2). Each item includes the Cisco DDTS tracking number, if applicable.
For INS Switch-type software (Japan), when you put a call on "hard-hold" and you are talking to another party (for example, a second call), you must disconnect the current call by hanging up (as opposed to using the flash) to return to the call on hold.
This section describes features of the Cisco 700 series router related to software Release 4.1(2).
Cisco Fast Step is supported by Cisco 700 series router software Release 4.1(1) and higher. It simplifies the setup, configuration, and monitoring of Cisco 700 series routers. Cisco Fast Step tests the setup connections and leads you step-by-step through the configuration process using Windows Wizards. Once the setup is complete, the monitor facility provides continuous router status and ISDN connection information.
Cisco Fast Step runs on Microsoft Windows 95 and Windows NT 4.0 systems for Cisco 700 series routers using software Release 3.2(5) or higher. Cisco Fast Step is available on the World Wide Web URL http://www.cisco.com/cgi-bin/getftp.pl/760. See the "Cisco Connection Online" section in this document for more information.
ClickStart EZSetup is supported by Cisco 700 series router software Release 4.1(1) and higher. It provides a web-based interface that guides you through a basic configuration. (Communications between the Cisco 700 series router and the configuration terminal is accomplished through the Ethernet by connecting both devices to an Internet Protocol (IP) network.)
For Cisco 700 series routers using software Release 4.0(1) or higher, ClickStart EZSetup is available on the World Wide Web URL http://cco/univercd/data/doc/clckstrt.htm. See the "Cisco Connection Online" section in this document for more information.
These are the enhancements for Cisco 700 series router software Release 4.1(1).
Cisco 700 series routers support three-way calling and call transfer. The required feature activation code, previously a fixed value, is now configurable for different central office switches. This feature activation code is available only for DMS/NI-1 ISDN switch types.
The automatic configuration feature allows the Cisco 700 series router to obtain a configuration file from a remote server by using BOOTP protocol. Upon power-up, the router examines the Auto_Config flag stored in NVRAM. If the Auto_Config flag is false, the router initiates the BOOTP to request an IP address from the server. If the server finds a matching MAC address, the server returns a client profile that includes an IP address and a configuration filename. The Cisco 700 series router then initiates TFTP to download the configuration file.
The Service Profile Identifiers (SPIDs) and switch types for U.S. software images must be entered or automatically detected before the router can run automatic configuration and download the configuration file. After successfully loading the configuration file, the router sets the Auto_Config flag to true in NVRAM. In the subsequent power-up operation, if the Auto_Config is true, the router does not initiate BOOTP. The set default command resets the Auto_Config flag to false.
If the router does not receive a BOOTP response from the server within 5 seconds of the first BOOTP request, the router gives up.
The SPID and switch autodetection feature simplifies the use of ISDN terminal equipment and makes the equipment easier to use with fewer parameters to enter. With this feature, you only have to enter the ISDN BRI directory (telephone) numbers with area codes. No SPID number or switch type is required. The command used is the set autodetection command.
The autodetection feature only applies to ISDN switches in the United States and Canada, which are usually 5ESS custom, DMS100 custom, NI-1, or NI-2 switches. The autodetection mechanism might not work with any other switch, such as a Siemens switch. The autodetection feature is only implemented in the Cisco software image for the United States and Canada.
The Bandwidth Allocation Control Protocol (BACP) and the Bandwidth Allocation Protocol (BAP) define a set of rules to gracefully control dynamic bandwidth allocation by managing the number of links in a Point-to-Point Protocol (PPP) multilink bundle. The BACP is a network control program that negotiates once per PPP multilink bundle, and BAP defines a set of request and response messages to manage the links.
The current release of Cisco 700 software already supports dynamic management of both B channels with the demand feature. The implementation of BACP and BAP allows Cisco 700 series routers to coordinate and negotiate the actual allocation and deallocation of the second channel.
Use of the negotiation features of BAP makes it unnecessary to require a common algorithm for determining when to add or remove a link in a multilink bundle. The parameters are set using the demand command and the timeout command.
The BACP is only implemented on the BRI interface. The multilink PPP has to be enabled for BACP to be functional.
This filtering scheme controls which services are added to the Cisco 700 series router Service Access Point (SAP) table. You can specify filters by type range or socket range. Before a service is added to the SAP table, the service type and socket number for the service is checked against the existing filters. If the type and socket ranges match any of the existing filters, service is permitted or denied based on the action specified in the action field of the filter. Otherwise (no filter matches the incoming service), the service is blocked. The parameters are set using the set ipx filter sap command. The maximum number of SAP filters is 20.
Version 4.0 of Cisco 700 software provides route summarization on IP RIP Version 2 (Version 2 provides the required subnet mask information). Version 4.1(1) of Cisco 700 software provides route summarization on IP RIP Version 1. IP RIP Version 1 learns and propagates Version 2 routes on destinations connected to the ISDN line for destinations connected to the LAN. When the route summarization is set to auto, the router summarizes routes that cross the classful boundary to a single route based on the classful boundary. When the route summarization is set to off, the router uses the normal RIP Version 2 routes with variable-length subnet masks (VLSMs). The default setting for RIP summarization is off. Use the set ip rip summarization command to control this feature.
Remote users often have multiple service providers. To connect to different service providers, remote users can have different user names and passwords. Previous releases of Cisco 700 software used the same user name and password for all profiles when making outgoing PPP connections. Software Release 4.1(1) allows different profiles to have different user names and passwords.
In previous releases, the set systemname command set the system prompt and the router identity when making outgoing PPP connections. In software Release 4.1(1), different profiles can use different identities, such as different user names, when dialing out. A new profile level command, the set ppp clientname command, has been created for this purpose.
The length of a character string for the user name and system name have been increased to 64 characters. The length of the password character strings has been increased to 30 characters.
Cisco 700 series routers use a TFTP client to increase TFTP file transfer efficiency and reliability. However, TFTP, as a simple protocol for software download, is rarely used during system run time. The swl command loads the TFTP client software from the console port.
A generic filter capability on the TCP/UDP packets allows users to filter NetBIOS packets generated by any application programs. Use the set ip filter command to control this feature.
When a WINS client sends out a NetBIOS Name query, if the router has the answer for the query, the Cisco 700 series router replies with response packets in place of the WINS server. Otherwise, the router forwards the query packets to the server and when the answer comes back, it forwards the response to the client. The router keeps a local database of up to 100 NetBIOS name entries and ages out the out-of-date entries.
The NetBIOS Scope option is implemented in Cisco 700 series router software Release 4.1(1) during configuration of the DNP server. NetBIOS Scope, also known as TCP/IP Scope, provides a method for adding a second element to the single-element NetBIOS computer name. The scope ID is a character string value that is appended to the NetBIOS name. The NetBIOS name is used for all NBT (NetBIOS over TCP/IP) communications from that computer.
Point-to-Point connections are made by using PPP. CPP is no longer supported by Cisco 700 software. Connections made by remote login are supported by PPP bridging.
This section describes the known limitations of software Release 4.1(1).
This feature assists in the installation of a Cisco 700 series router in North America. It determines the service profile identifier (SPID) and the switch protocol that connects the router to the network. This is done by following a prescribed SPID and switch type table search, followed by a test call. You must enter the primary directory numbers (with the area code) and invoke the detection feature by using the set autodetection command to find the SPIDs.
The following limitations are inherent in SPID autodetection:

Step 6 Select the file you saved in Step 3 in the "Saving a Configuration" section.
Step 7 Click OK. The parameters are transferred to your router.
Step 8 If errors occur during the transfer, enter the set default command, increase the delay between lines, and repeat the procedure for loading new software and reloading the configuration, beginning with Step 1.
Cisco 760 series and Cisco 770 series routers require 1.5 MB of dynamic random-access memory (DRAM) to run software Release 4.0(1) and higher. If it is necessary to upgrade the DRAM in your router, see the Cisco 700 Series Installation Guide for instructions.
Cisco 770 series routers are shipped with 1.5 MB of DRAM. Cisco 761, Cisco 762, Cisco 765, and Cisco 766 routers shipped after September, 1996, contain 1.5 MB of DRAM. The Cisco models 765-US, 765-CA, 765-CE, 765-NL, 765-UK, 766-US, and 766-CA shipped before September, 1996, contain 1 MB of DRAM. You must add at least 0.5 MB of DRAM to these router models to run software Release 4.0(1) and higher.
If you are running Cisco 700 software Release 3.2(4) or greater, use the show memstat command to find the total memory installed in your Cisco 700 series router. The following shows a typical show memstat command output:

The RAM Size entry indicates the amount of DRAM installed, reported in hexadecimal. Table 3 lists the RAM size hexadecimal values reported by the show memstat command and the corresponding RAM size in megabytes.
RAM Size (hex) | Memory |
---|---|
0x100000 | 1 MB |
0x180000 | 1.5 MB |
0x200000 | 2 MB |
If you do not have at least 1.5 MB of DRAM in your Cisco 700 series router you cannot run software Release 4.0(1) or higher. You can install another 0.5 MB of DRAM or, if you downloaded software Release 4.0(1) and the device will not boot because you do not have enough DRAM, you can reload Cisco 700 software Release 3.2(5).
To Cisco 700 software Release 3.2(5):
Step 1 Power up the router.
Step 2 As soon as the boot banner appears, press the ESC key.
Step 3 Read and follow the software load command instructions in the Cisco 700 Series Command Reference publication if you are loading from a floppy disk or the instructions in the CD booklet if you are loading from a CD.
Step 4 Read and follow the set defaults command instructions in the Cisco 700 Series Command Reference publication.
Complete the following tasks to upgrade to software Release 4.1(1):
A capability package is a set of standardized BRI line features that simplifies the process of configuring an ISDN line. The capability package ordering codes described in this section apply to NI-1 ISDN lines.
Package S provides alternate voice and circuit-switched data with no additional features. Package S is the preferred NI-1 capability package for Cisco 765, Cisco 766, Cisco 775, and Cisco 776 routers when a minimum feature set is needed.
Package EZ-1 (also refered to as Capability Package U) provides alternate voice and circuit-switched data with all the features and capabilities of the router enabled. Package EZ-1 is the preferred NI-1 capability package for the Cisco 765, Cisco 766, Cisco 775, and Cisco 776 routers when a full feature set is needed. The features include flexible calling (conference calling, call transfer, hold and retrieve), ACO (call waiting), and Call Forward Busy (CFB).
If you have any problems with your ISDN NI-1 provisioning, contact Cisco ISDN Support Services (United States only). To access this service or to obtain more information, call (800) 553-NETS (6387) and select the Customer Service option, or visit the Cisco ISDN web site at www.cisco.com/isdn.
When provisioning multiple directory numbers for a 5E-NI1, additional provisioning information is available from Cisco ISDN Support Services. With this provisioning change, the distinctive ringing feature is activated; however, the flexible calling features (three-way conference calling call transfer, hold and retrieve) are not available.
ISDN Support Services are only available in the United States, effective May 27, 1997. To access this service or to obtain more information, call 800 553-NETS (6387) and select the Customer Service option, or visit the Cisco ISDN Web site at www.cisco.com/isdn.
