Introduction

The four-port synchronous (sync) serial network module (NM-4T) has four DB-60 ports and provides a data rate of 8 Mbps on port 0, 4 Mbps each on port 0 and port 2, or 2 Mbps on all four ports simultaneously. The NM-4T network module only supports sync mode. The DB-60 ports on the NM-4T network module support the Cisco 60-pin "5-in-1" cables used on the Cisco 2500 and Cisco 7000 series routers.

Product Number

NM-4T - Four-Port Sync Serial Network Module

Features

• Four serial ports.

• Uses Cisco DB-60 connectors (same cabling as Cisco 2500, Cisco 7000, NM-4A/S, and NM-8A/S). For more information, refer to 60-pin "5-in-1".

• Supports sync mode only (async mode is not supported).

• Provides synchronous data rate of 8 Mbps on port 0, 4 Mbps each on port 0 and port 2, or 2 Mbps on all four ports simultaneously.

• Does not support bisync or half-duplex.

Platform Support

Note: The Cisco IOS Software releases provided are typically the minimum version required in order to support the platform, module, or feature in question. Use the Software Advisor (registered customers only) to choose appropriate software for your network device, match software features to Cisco IOS Software and CatOS releases, compare Cisco IOS Software releases, or find out which software releases support your hardware.

Configuration

On the NM-4T network module, the interfaces are addressed as interface serial slot/unit . The units are numbered from right to left. This output is a sample configuration for the NM-4T network module. Configure the NM-4T as you would any other serial interface on a 2500, 7500, and so forth.

Note: There are no framing, clocking, or linecode parameters or commands used in this configuration. The NM-4T network module does not have an integrated CSU/DSU. You need to use an external CSU/DSU.

maui-soho-02(config)# interface Serial 2/0
maui-soho-02(config-if)# ip add 10.0.0.1 255.255.255.0
maui-soho-02(config-if)# encapsulation ppp
maui-soho-02(config-if)# no shutdown

For more information on configuring the NM-4T network module, refer to Configuring Serial Interfaces.
