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:  
Note  
Note  
Unless specifically identified, references to PRI modules in this chapter include all these network  
modules.  
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-in channel service unit (CSU), and with one or  
two ports. CT1/PRI modules connect to an external CSU; CT1/PRI-CSU modules 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.

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.

Warning  
For connections outside the building where the equipment is installed, the following ports must be  
connected through an approved network termination unit with integral circuit protection: T1  
Statement 1044  
Figure 4 shows a connection between a channelized T1/E1 PRI network module with G.703 and a  
networking device.  
Caution  
To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety,  
connect the 1-port T1/E1 channelized PRI network modules with G.703 (NM-1CE1T1-PRI) and 2-port  
T1/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.

CE1/PRI-B ports  
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-ohm CE1/PRI-B modules disconnects receive shield to  
ground. The default setting for unbalanced, 75-ohm CE1/PRI-U modules 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.

CE1/PRI-B port to an E1 CSU. (See Figure 13, Figure 14, and Figure 15, showing DB-15, twinax, and  
RJ-45 CSUs, respectively.) These ports are color-coded tan.

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, or NM-30DM), your  
ISDN PRI network module may need to be upgraded to revision level -03 or 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 800- and ending with the revision level.  
The output of the show diag command looks similar to the following:
