Connecting Cisco ISDN PRI Network Modules to the Network

Revised: May 1, 2008, OL-12811-01

This guide describes how to connect Cisco Integrated Services Digital Network (ISDN) Primary Rate Interface (PRI) network modules to your network. It contains the following sections:

Channelized T1/E1 PRI Network Modules with G.703, page 2

Channelized T1/ISDN PRI Network Modules, page 5

Channelized T1/ISDN PRI with CSU Network Modules, page 6

Channelized E1/ISDN PRI Balanced (120-Ohm) Network Modules, page 7

Channelized E1/ISDN PRI Unbalanced (75-Ohm) Network Modules, page 10

PRI Module LEDs, page 11

Online Insertion and Removal with a Cisco PRI Network Module (Cisco 3660 and Cisco 3745 Only), page 14

Upgrading ISDN PRI Network Modules, page 15

Related Documents, page 15

Obtaining Documentation, Obtaining Support, and Security Guidelines, page 16

Note Unless specifically identified, references to PRI modules in this chapter include all these network modules.

Note Do not install an ISDN BRI network module in the same chassis as an ISDN PRI network module, unless you are using Cisco IOS Release 11.3(3)T or later. Earlier Cisco IOS releases do not support this configuration.

CT1/PRI modules are available with or without a built-inchannel service unit (CSU), and with one or two ports. CT1/PRI modules connect to an external CSU;CT1/PRI-CSUmodules connect directly to the network. Each T1 module provides up to 24 virtual channels per T1 port. Each channel can be configured individually as a serial interface.

Channelized T1/E1 PRI Network Modules with G.703

CT1/PRI and CT1/PRI-CSUmodules receive and transmit data bidirectionally, at the T1 rate of 1.544 Mbps.

Channelized T1/E1 PRI Network Modules with G.703

This section provides information about the following network modules:

1-portT1/E1 channelized PRI network module with G.703(NM-1CE1T1-PRI)(seeFigure 1)

2-portT1/E1 channelized PRI network module with G.703(NM-2CE1T1-PRI)(seeFigure 2)

Cisco T1/E1 channelized PRI network modules with G.703 provide connection of one or two primary rate ISDN lines. T1 or E1 interfaces are configurable through Cisco IOS command-lineinterface (CLI) commands. Each port supports100/120-ohmbalanced and75-ohmunbalanced termination, and featuresRJ-48Cconnectors and cable accessories allowing forDB-15,BNC, and other connector types. An onboard advanced integration module (AIM) connector allows for future universal port AIM support.

Caution To comply with the TelcordiaGR-1089NEBS standard for electromagnetic compatibility and safety, connect the1-portT1/E1 channelized PRI network modules with G.703(NM-1CE1T1-PRI)and2-portT1/E1 channelized PRI network modules with G.703(NM-2CE1T1-PRI)only to intrabuilding or nonexposed wiring or cabling. The intrabuilding cable must be shielded and the shield must be grounded at both ends.

Cisco T1/E1 channelized PRI network modules with G.703 (NM-1CE1T1-PRIandNM-2CE1T1-PRI)replace the following network modules (also described in this chapter):

NM-1CE1B

NM-1CE1U

NM-1CT1

NM-1CT1-CSU

NM-2CE1B

NM-2CE1U

NM-2CT1

Enabling Wetting Current on Channelized T1/E1 PRI Network Modules with G.703

Wetting current is a small amount of electrical current (60 to 140 milliamps) sent from the central office to the card to prevent the corrosion of electrical contacts in the module network connection.

The wetting current feature can be enabled or disabled by the end user. It is controlled by the location of a jumper on the J8 (CTLR 0) and J9 (CTLR 1) connectors on the network module. (See Figure 3.)

To enable the wetting current feature, connect pins 1 and 2 on the J8 and J9 connectors with the jumper. To disable the wetting current feature, either remove the jumper completely, or use the jumper to connect pins 2 and 3 on the J8 and J9 connectors.

The card is shipped with the jumper connecting pins 2 and 3 on the J8 and J9 connectors, disabling the wetting current feature.

CE1/PRI-Bports

CE1/PRI modules are available with one or two E1 ports and with balanced or unbalanced interfaces. These modules receive and transmit data bidirectionally at the E1 rate of 2.048 Mbps, and provide up to 30 virtual channels per E1 port. Each channel can be configured individually as a serial interface.

CE1/PRI Module Jumper Settings

Jumpers on CE1/PRI modules can be used to connect or disconnect receive shield to ground. (See Table 2.) The default setting for balanced,120-ohmCE1/PRI-Bmodules disconnects receive shield to ground. The default setting for unbalanced,75-ohmCE1/PRI-Umodules connects receive shield to ground. If you are experiencing ground loop problems with E1 cabling, you may want to try changing the jumper settings for the module.

Online Insertion and Removal with a Cisco PRI Network Module (Cisco 3660 and Cisco 3745 Only)

Some Cisco modular access routers allow you to replace network modules without switching off the router or affecting the operation of other interfaces. This feature is called online insertion and removal (OIR). OIR of network modules provides uninterrupted operation to network users, maintains routing information, and ensures session preservation.

Note To determine if your router supports OIR, see the hardware installation guide for your router.

Caution Cisco routers support OIR with similar modules only. If you remove a network module, install another module exactly like it in its place. If you remove a network module with an installed interface card, expansion module, or AIM, the replacement module should have the same hardware installed.

For a description of informational and error messages that may appear on the console during this procedure, refer to the hardware installation guide for your type of router.

Upgrading ISDN PRI Network Modules

Upgrading ISDN PRI Network Modules

If your Cisco 3600 series router contains a legacy ISDN PRI network module and a digital modem network module (product numbers NM-6DM,NM-12DM,NM-18DM,NM-24DM,orNM-30DM),your ISDN PRI network module may need to be upgraded to revision level-03or higher. Earlier revisions of ISDN PRI network modules cannot send modem calls to the digital modem network module.

Note Channelized T1/E1 PRI network modules with G.703 provide full support for Cisco digital modem network modules.

If your PRI module is the wrong revision, you see a message similar to the following message when the router boots:

The PRI network module in slot 0 is incompatible with the digital modems installed in the router.

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 800and ending with the revision level.

The output of the show diag command looks similar to the following:
