This section provides the latest information about Cisco 700 series router software Release 4.2(1) limitations. Each item includes the Cisco DDTS tracking number, if applicable.
The Multilink Point-to-Point (MLPPP) implementation uses End-Point Discriminator (EPD, which is the MAC address in the case of Cisco 700 series routers) to identify a MLPPP bundle. (EPD prevents congestion that would otherwise jeopardize the ability to properly support existing connections.) If making two separate connections from two profiles, the Cisco 700 series router treats the two connections as one MLPPP bundle because both connections use the same remote EPD. MLPPP only works if two separate connections are made to two different routers, which will have two different EPDs.
Cisco 700 series router software Release 4.2(1) does not support MLPPP link-level fragmentation. When there is only one link in the MLPPP bundle, the Cisco 700 series router MLPPP layer does not fragment an MLPPP frame, even if the frame size is bigger than the maximum receive unit (MRU) of the remote router.
This section provides the latest information about Cisco 700 series router software Release 4.2(1) caveats. Each item includes the Cisco DDTS tracking number, if applicable.
Due to the limitations of logical switched virtual circuits (LSVC), an FTP session over the D channel locks the idle time on all LSVCs until the FTP session terminates. Any activities other than the FTP session, such as ping or Telnet, with the same network destination do not time out. For example, if there is an FTP session on LSVC 1 and you ping a device on the same network using LSVC 2, the idle time locks; the LSVCs remain open, even if ping is finished and there is no traffic on the LSVC. (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)
When a router configured as a DHCP server is power cycled, the IP address issued from the router is lost to the router table. A second PC trying to get an IP address from the router receives the IP address at the top of the list, duplicating the first PC IP address. (CSCdj45244)
X.25 call setup fails if the ISDN line is disconnected. This has been resolved in software Release 4.2(1). (CSCdj53139)
The router is unable to flash back a call on hard hold when running the INS version of the software. This has been resolved in software Release 4.2(1). (CSCdj59027)
Dial-on-Demand stops functioning after one or more successful calls. This has been resolved in software Release 4.2(1). (CSCdj60902)
A fatal IP packet causes the system to hang. This has been resolved in software Release 4.2(1). (CSCdj64735)
A system-level password that exceeds the character limit of the feature causes the router to stop working. This has been resolved in software Release 4.2(1). (CSCdj66458)
When the ISDN line is unplugged from a remote device while the devices were communicating, the Link Access Procedure, Balanced (LAPB) state does not reset properly. This has been resolved in software Release 4.2(1). (CSCdj53139)
The IP route command disappears. This has been resolved in software Release 4.2(1). (CSCdj63426)
Support for one-digit ISDN dialing is missing. This has been resolved in software Release 4.2(1). (CSCdj70173)
The IP filter ignore does not work. This has been resolved in software Release 4.2(1). (CSCdj81706)
Incoming voice calls are rejected when a data call is connected. This has been resolved in software Release 4.2(1). (CSCdj87218)
NETBIOS only retains name entries for a short time if a dynamic IP address is assigned. This has been resolved in software Release 4.2(1). (CSCdj80349)
When the config upload command is used in a Telnet session, lines are missing. This has been resolved in software Release 4.2(1). (CSCdj80519)
Continuous incoming calls cause a busy tone the router is in auto detection mode. This has been resolved in software Release 4.2(1). (CSCdj78437)
The first time a system password is entered, it is echoed through the ISDN connection. This has been resolved in software Release 4.2(1). (CSCdj81519)
Unnecessary Token Authentication Support (TAS) error messages display when there is no token. This has been resolved in software Release 4.2(1). (CSCdj82185)
Point-to-Point Protocol (PPP) data drop occurs if the maximum transmission unit of a remote router has a maximum receive unit (MRU) bigger than the remote MRU. This has been resolved in software Release 4.2(1). (CSCdj81840)
This section describes the applications supported by the Cisco 700 series router software Release 4.2(1).
CiscoSecure Authentication Agent is a windows application running on Windows 95 and Windows NT 4.0. It simplifies the use of token authentication over ISDN and changes expired CiscoSecure passwords. There are two authentication modes for CiscoSecure Authentication Agent, single authentication mode and double authentication mode. The Cisco 700 series router operates in single authentication mode when Token Authentication Support (TAS) is turned on. CiscoSecure Authentication Agent is available on the World Wide Web. 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 Setup application tests the network connections and leads you step-by-step through the router configuration process. Once the setup is complete, the Cisco 700 Fast Step Monitor utility provides continuous router status and ISDN connection information.
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. It is also available on Cisco Connection Online. See the "Cisco Connection Online" section in this document for more information.
Cisco 700 series router software Release 4.0(1) and higher supports ClickStart EZSetup. It provides a web-based interface that guides you through a basic router 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 Cisco Connection Online. See the "Cisco Connection Online" section in this document for more information.
This section describes the process for saving the current configuration and updating the router software image.
Images for Cisco 700 series router 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 "Upgrading the DRAM in a Cisco 700 Series Router" section for instructions on checking the amount of DRAM, and increasing it.
X.25 images Cisco 700 series router software Release 4.2(1) and higher require 1.5 MB of DRAM and 1 MB of Flash memory. If you do not have enough Flash memory to run X.25 images, the router must be replaced 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.
The following example saves the configuration to a file by using Terminal for Windows, a common terminal emulation software program:
Step 1 When the terminal emulation program is running, enter the upload command at the command line prompt, but do not press Return after you enter the command:
Step 2 From the Transfer menu, select Receive Text File.
Step 3 In the Receive Text dialog box, specify a filename to save the configuration in, and select the directory where you want to save the file.
Step 4 Click OK.
Step 5 Return to the terminal emulation program, and press Return to execute the command. The configuration is saved to the file specified in Step 3.
Step 6 Click Stop when the configuration has finished uploading. You are ready to download the software.
Select the image (filename) for your router. Table 1, Table 2, and Table 3 list the filename and memory required for each image. Images named C760 work for both Cisco 760 and Cisco 770 series routers.

Cisco 700 series routers require 1.5 MB of DRAM to run non-X.25 images of software Release 4.0(1) and higher. (X.25 images require 1.5 MB of DRAM and 1 MB of Flash memory. 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 higher, use the show memstat command to find the total memory installed in your Cisco 700 series router. The following example shows a typical show memstat command output:

|---|---|
| 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. If you downloaded software Release 4.0(1) and the device does not boot because you do not have enough DRAM, you can reload Cisco 700 software Release 3.2(5).
To load Cisco 700 series router 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 If you are loading software from a floppy disk, read and follow the swl (software load) command instructions in the Cisco 700 Series Command Reference. If you are loading software from a CD, read and follow the swl (software load) command instructions in the CD booklet.
Step 4 Read and follow the set defaults command instructions in the Cisco 700 Series Command Reference.
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. When a minimum feature set is needed, Package S is the preferred NI-1 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 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. 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.
