The Cisco ® T3/E3 Network Module provides high-speed WAN access for the Cisco 2600, 2800, 3600, 3700 , 3800 Series routers, as well as the Cisco 2951, and 3900 Series Integrated Services Routers. The NM-1T3/E3 network module offers both Service Providers and Enterprise customer's unprecedented flexibility in provisioning clear-channel T3 or E3 connections.
Figure 1. Cisco T3/E3 Network Module
Cisco's Packet-over-T3/E3 network module for the Cisco Integrated Services Routers series offers the first software-configurable T3/E3 product from Cisco. This flexible network module allows the customer to switch between T3 and E3 applications with a single Cisco IOS ® command. This feature provides customers increased flexibility and investment protection by allowing a Cisco Partner, service provider or enterprise customer to stock only a single product that can be deployed internationally.
The increased demand for bandwidth over the WAN and more attractive pricing of T3/E3 links by SPs has led to steady growth in T3/E3 deployments around the world. The Packet-over T3/E3 network module (part number NM-1T3/E3) eliminates the need for an external data service unit (DSU), reduces provisioning costs, and provides highly manageable T3/E3 line termination. The module provides an integrated line interface unit (LIU) DSU that allows T3 or E3 lines to be directly terminated on a Cisco router, eliminating the need for external DSU equipment. This simplifies the T3/E3 line management, reduces provisioning cost, and frees up valuable rack space.
The Cisco T3/E3 network modules provide support for the proprietary subrate and scrambling features of T3 DSU vendors such as Digital Link, Larscom, and ADC Kentrox. Subrate support in the Cisco T3/E3 Network Module maximizes the utility of these products in service provider environments By simultaneously supporting interoperability with a wide range of third-party DSU vendors, this network module offers the flexibility to support installed equipment without locking customers into a proprietary solution.
The Cisco T3/E3 Network Module provides direct connectivity to a T3 line for full-duplex communications at the T3 rate of 44.736 MHz and full-duplex E3 communications at 34.368 MHz. Each T3 or E3 port consists of a pair of 75-ohm BNC coaxial connectors (Type RG-59), one for transmit data and one for receive data, along with six LED indicators for line status. The Cisco T3/E3 Network Module is supported in all Cisco IOS feature sets, and there are no additional memory requirements.

Prerequisites for Connecting 1- and 2-Port Serial WICs to a Network
Before connecting a WIC to the network, ensure that the WIC is installed in the router, the equipment is properly grounded, and you have the proper cables for connecting the WIC to the network. This section describes the preparation necessary before connecting a 1- and 2-Port WIC to the network.
Installing a Cisco Serial WAN Interface Card
Install the Cisco serial wan interface card according to the instructions in Installing Cisco Interface Cards in Cisco Access Routers .
Grounding
Ensure that the equipment you are working with is properly grounded according to the instructions in Installing Cisco Interface Cards in Cisco Access Routers .
Cables
After you install the serial WIC, use the appropriate serial cable to connect the WIC’s serial port to one of the following types of equipment. (See Figure 5.):
- An asynchronous modem, if connecting to an analog telephone line
- A synchronous modem, DSU or CSU, or other DCE, if connecting to a digital WAN line
The 1-port serial WIC has a DB-60 serial port, whereas the 2-port serial WIC and the 2-port A/S WIC have Cisco smart serial ports. Use the correct cable for your serial WIC.
The serial cable attached to a smart serial port determines the port’s electrical interface type and mode (DTE or DCE).
Caution Do not over-torque the screws on the serial cable when attaching to the serial WAN interface card. Recommended torque is 2.0 kgf.cm (1.7 lbf.in). Over-torquing may cause damage to the interface card.
Tip A cable providing surge protection (CAB-SS-SURGE) is also available from Cisco Systems. See the “For connection limitations, see the “1- and 2-Port Serial WICs” section on page 1, and the “2-Port Asynchronous/Synchronous Serial WIC” section on page 2.” section for instructions on connecting the surge protector cable.
Types of Cables for 1- and 2-Port Serial WICs
Six types of serial cables (also called serial adapter cables or serial transition cables ) are available from Cisco Systems for 1- and 2-port serial WICs:
- EIA/TIA-232 serial cable assembly
- EIA/TIA-449 serial cable assembly
- V.35 serial cable assembly
- X.21 serial cable assembly
- EIA/TIA-530 serial cable assembly
- EIA/TIA-530A serial cable assembly
All serial cables provide a universal plug at the interface card end. The network end of each cable provides the physical connectors most commonly used for the interface. For example, the network end of the EIA/TIA-232 serial cable is a DB-25 connector, the most widely used EIA/TIA-232 connector.
All serial interface types except EIA-530 are available in DTE or DCE format: DTE with a plug connector at the network end and DCE with a receptacle at the network end. V.35 is available in either mode with either gender at the network end. EIA-530 is available in DTE only.
Caution Do not over-torque the screws on the serial cable when attaching to the serial WAN interface card. Recommended torque is 2.0 kgf.cm (1.7 lbf.in). Over-torquing may cause damage to the interface card.
