differ in the number of interfaces supported. Some information provided might not apply
to your particular router model.

How to Use This Guide

This guide contains an overview of network modules and information on connecting
specific network modules to your Cisco modular router. Refer to Table 1-1 in Chapter 1,
"Overview of Cisco Network Modules" for a listing of network modules supported by
Cisco 3600 series routers and the required release of Cisco IOS software for each module.

    Signaling Standards Supported The synchronous serial ports available for the router support the following signaling standards: EIA/TIA-232, EIA/TIA-449, V.35, X.21, and EIA-530. You can order a Cisco DB-60 shielded serial transition cable that has the appropriate connector for the standard you specify.
  • Page 55: Distance Limitations

    The synchronous serial port can be configured as DTE or DCE (except EIA-530, which is DTE only), depending on the attached cable. To order a shielded cable, contact customer service. (See the Cisco Information Packet publication that came with your router.) All serial ports configured as DTE require external clocking from a CSU/DSU or Note other DCE device.
  • Page 56 EIA/TIA-232 serial ports. Depending on the type of cable, the network end consists of either RJ-45 plugs or male DB-25 connectors. RJ-45-to-DB-25 adapters are also available. Cisco Network Modules Hardware Installation Guide...
  • Page 57 RJ-45 to DB-25 adapter Asynchronous Network Modules Interface Numbering Certain Cisco IOS configuration commands identify asynchronous ports by an interface number (or a line number, which is the same as the interface number). The interface number of a port on a asynchronous network module is related to the slot number where the module is installed and the unit number of the port in the module.
  • Page 58 For example, Cisco 3620 router slots are numbered 0 and 1, as shown in Figure 6-2. In Cisco 3640 routers, the bottom row of slots is numbered 0 and 1 and the top row is numbered 2 and 3, as shown in Figure 6-3.

  • Page 60 Asynchronous Network Modules Interface Numbering Cisco 2600 Series Asynchronous Port Interface Numbering Interface numbering for Cisco 2600 series routers differs from Cisco 3600 series interface numbering in the following ways: • WAN interface card slot numbers always appear as slot 0, even if the interface card is installed in the slot labeled W1.
  • Page 61 49–56 Cisco 3640 router only. To prevent this conflict, Cisco IOS Release 11.2(7)P, which is required to operate 16-port and 32-port asynchronous network modules, checks when it boots for the presence of 4-port and 8-port asynchronous/synchronous network modules configured as asynchronous.

  • Page 103 These sections describe how to connect 6-, 12-, 18-, 24-, and 30-port digital modem network modules (Cisco product numbers NM-6DM, NM-12DM, NM-18DM, NM-24DM, NM-30DM) for Cisco modular routers. (See Figure 10-1.) These modules contain 6, 12, 18, 24, or 30 V.34+ digital modems for a direct digital connection to an Integrated Services Digital Network (ISDN) Primary Rate Interface (PRI) or Basic Rate Interface (BRI) channel, allowing you to mix digital and analog calls to provide remote access to a LAN.
  • Page 104 Each digital modem module contains from one to five banks of 6-port modem ISDN channel aggregation (MICA) modules. You can add modems to a module, in groups of six, by installing additional MICA modules (Cisco product number MICA-6MOD=), up to a maximum of 30 modems.
  • Page 105: Hardware Requirements

    To determine the revision level, you can examine the network module itself (outside the router), or use the Cisco IOS show diag command. The label on the module board should show a part number beginning with 800- and ending with -03 or -06. A PRI or BRI S/T module whose part number ends with -01 or -02 needs to be upgraded, as does a BRI U module whose part number is lower than -06.
