Cisco Catalyst 4000 Access Gateway Module Installation and Configuration Note

OL-3008-01

Chapter 2 Installing the Access Gateway Module

Connecting the Voice and WAN Interface Modules

The 2-port A/S serial module has “smart” serial ports. The serial cable attached to one of the module’s

ports can determine the electrical interface type and mode (DTE or DCE).

Six types of serial cables (also called serial adapter cables or serial transition cables) are available from

Cisco Systems for use with the 2-port A/S serial module:

• 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 module end. The network end of each cable

provides the physical connectors that are most commonly used for the interface. For example, the

network end of the EIA/TIA-232 serial cable is a DB-25 connector, which is the most widely used

EIA/TIA-232 connector.

All serial interface types except EIA-530 are available in the following DTE or DCE mode: DTE with a

plug connector at the network end and DCE with a receptacle at the network end. The V.35 assembly is

available in either mode with either gender at the network end. The EIA/TIA-530 assembly is available

in DTE only.

After you install the 2-port A/S serial module, use the appropriate serial cable to connect the serial port

on the module to one of the following types of equipment (see Figure 2-7):

• Synchronous modem

• DSU/CSU

• Other DCE, if connecting to a digital WAN line

To connect either the 1- or 2-port serial module, perform these steps:

Step 1 Power of the AGM.

Step 2 Connect one end of the appropriate serial cable to a DB-60 port on the module, as shown in Figure 2-7.

Step 3 Connect the other end of the cable to the appropriate type of equipment, as shown in Figure 2-7.
