This section explains the following:
The heart of the Release 4.2(3) software feature pack for Cisco 700 series routers is a software image stored on CD-ROM. The feature pack box contains the following:
Table 1 in this section identifies each feature pack as specified on the router software CD-ROM label and describes the feature sets in each feature pack. The table also lists the following: UNIX and DOS filenames of the images, router platform on which each feature set runs, and memory requirements for each feature set.
Images for software Release 4.0(1) and higher require 1.5 MB of dynamic RAM (DRAM). If you do not have enough DRAM to support the software, the router does not boot. Refer to the "National ISDN Capability Packages" section for instructions on checking the amount of DRAM. Instructions for increasing the amount of DRAM are in the Cisco 700 Series Installation Guide.
X.25 images require 1.5 MB of DRAM and 1 MB of Flash memory. If your router does not have enough Flash memory to run X.25 images, you must replace it with a Cisco 700M series router. The label on the bottom of the router identifies an M-series router. You can display the amount of Flash memory by using the version command. Refer to the Cisco 700 Series Command Reference for information about this command.

Running X.25 over the ISDN D channel requires 1 MB of Flash memory on a Cisco 700 router. If your router has a Flash memory size of 0.5 MB and you plan to run X.25 over the ISDN D channel, contact your Cisco Sales Representative to trade in your Cisco 700 router.
The Cisco 700 series router software Release 4.2(3) provides the following enhancements:
In the IR image for software Release 4.2(3), the number of users allowed is increased to 30.
Some network equipment requires that the router send an alert message. In software Release 4.2(3), the Cisco 700 series router sends an alert message when answering a call. (CSCdk26667)
This section provides the latest information about Cisco 700 series router software Release 4.2(3) limitations. Each item includes the Cisco DDTS tracking number, if applicable.
During the upload of a configuration over ISDN the line, the DEMAND 1 DURATION statement is missed. This has been resolved in software Release 4.2(3). (CSCdj80519)
In the 1tr6 image, if you are connected on a voice call and flash, the message "Warning: Illegal dereference" displays and the router might reboot. This has been resolved in software Release 4.2(3). (CSCdk03329)
The Cisco 700 series router telnet server does not give up by timeout. The router calls the Telnet client every 2 minutes and does not stop. The condition is created as follows:
This has been resolved in software Release 4.2(3). (CSCdk11798)
AO/DI is available only on one connection. Even if it is enabled on multiple profiles, only one profile at a time can use it. (no number available)
When TAS mode is on, the Cisco 700 series router continuously attempts to authenticate after a failed login. For example, a user launches a Web browser but does not enter a login ID. The connection to the CiscoSecure Authentication Agent times out (as it should); however, the router continues to retry the connection. During the subsequent retries, the router sends its own authentication information, not the authentication information of the user. This results in sessions going up and down continuously. This has been resolved in software Release 4.2(3). (CSCdk24138)
To save the router configuration file on your PC, load new software, and then reload the configuration to the router, refer to the "Getting Started with Cisco 700 Series Software" CD booklet shipped with your software feature pack.
The default image for Cisco 761, Cisco 765, Cisco 771, and Cisco 775 routers is NET3, IR. The default image for all other Cisco 700 series routers is U.S.
This section describes how to configure your router to operate with the network central office switch. Table 3 describes each switch type. The default switch type is dependent upon the system software version.
| Switch Type | Description |
|---|---|
5ess | AT&T 5ESS |
dms | |
ni-1 | National ISDN-1 |
ins | |
net3 | |
1tr6 | |
tph | |
perm64 | |
perm128 |
To configure your router to operate with the network central office switch, use the command set switch from the system level command mode. The following example configures the ISDN switch type as DMS:
Host> set switch dms
Table 4 lists the commands available to use for each switch type and location:
| Switch Type | Location | Command to Set the Switch Type |
|---|---|---|
5ess, dms, ni-1 | U.S. | SEt SWitch {5Ess | DMS | NI-1 | PERM64 | PERM128} |
ins | Japan | SEt SWitch {INS | PERM64 | PERM128} |
net3 | Europe | SEt SWitch {NET3 | PERM64 | PERM128} |
1tr6 | Germany | SEt SWitch {lTR6 | PERM64 | PERM128} |
tph | Australia | SEt SWitch {TPH | PERM64 | PERM128} |
perm64, perm128 | U.S., Japan, Europe, Germany, Australia | SEt SWitch {PERM64 | PERM128} |
This section provides the latest information about Cisco 700 series router software Release 4.2(3) caveats. Each item includes the Cisco DDTS tracking number, if applicable.
Windows NT clients fail to browse for a Windows NT server as a result of the following condition:
In software Release 4.2(3), the Cisco 700 series router checks the IPX destination network field in the NetBIOS packet. If the network number field is not zero, the router changes the field to zero and forwards the packet to the LAN. (CSCdk20359)
RIP updates keep the ISDN link up if the idle timeout is greater than the RIP timer value, even if the RIP option is linkup. However, it does not cause the link to come up by itself. To correct the problem, use a filter for RIP traffic with the ignore option in the WAN profile. (no number available)
The system password is echoed over the ISDN connection the first time the connection is established. However, it is not echoed in subsequent connections. (no number available)
The upload command does not include the set ip route destination 0.0.0 propagate off conv1 command in the configuration if a default route was entered in the user-defined profile before the connection was made. This occurs when the router connects to an Internet service provider, and obtains an IP address through IP control protocol (IPCP) negotiation. (no number available)
A router repeatedly receives voice calls when both B channels are occupied with data calls intermittently loses one of the B channels. To correct the problem, reboot the router. (CSCdj68840)
This section describes the applications supported by the Cisco 700 series router software Release 4.2(3).
The CiscoSecure Authentication Agent (available for Windows 95 and Windows NT 4.0) application simplifies the use of token authentication over ISDN. There are two authentication modes: single authentication and double authentication.
The Cisco 700 series router operates in single authentication mode when Token Authentication Support (TAS) is enabled. CiscoSecure Authentication Agent is available on the World Wide Web (WWW). See the "Cisco Connection Online" section in this document for more information.
Cisco 700 series router software Release 4.0(1) and higher supports Cisco 700 Fast Step. Cisco 700 Fast Step simplifies the setup, configuration, and monitoring of Cisco 700 series routers.
Cisco 700 Fast Step runs on Microsoft Windows 95 and Windows NT 4.0 systems. It is provided with your router on the Cisco Fast Step CD-ROM. The application is also available on Cisco Connection Online. See the "Cisco Connection Online" section in this document for more information.
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 NI1.
Package S provides alternate voice and circuit-switched data with no additional features. When a minimum feature set is needed, Package S is the preferred NI1 capability package for Cisco 765, Cisco 766, Cisco 775, and Cisco 776 routers.
Package EZ-1 (also referred 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 NI1 capability package for the Cisco 765, Cisco 766, Cisco 775, and Cisco 776 routers. 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 NI1 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 NI1, additional provisioning information that activates the distinctive ringing feature is available from Cisco ISDN Support Services; 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. 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.
All documents mentioned in this section are available in electronic format. (See the section "Online Navigation" section for more information on accessing electronic documentation.)
The following documentation is related to these release notes:
The following documentation is provided with your Cisco 700 series router:
This section provides information that was not included in the current documentation and is not available elsewhere. The information will be included in the next revision of the documentation.
The Cisco 700 series router attempts to establish a connection with the remote host whenever interesting traffic is queued to be sent over a WAN connection. When bridging is off, the router attempts to connect to the remote device when IP traffic is queued. When bridging is on (default), the router attempts to connect when IP traffic and all nonrouted traffic is queued.
It is recommended that bridging be set to off in a WAN profile to reduce the amount of interesting traffic, and therefore, the number of attempts made to establish a connection. If the remote connection goes down, the router continuously attempts to bring up the line. In some environments (most commonly Windows NT using only Netbios), this causes the line to dial continuously. Depending on your configuration and how your connection is billed, turning bridging off in the WAN profile might reduce your costs.
For example, in the configuration titled "Routing IP On Demand," which begins on page 3-16 of the Cisco 700 Series Installation Guide (DOC-78241=), you should enter the command set bridge off near Step 11. The exact sequence of this command in relation to the other commands is not critical, as long as it is done in the central902 profile.
