(120-ohm) Network Modules
This section provides information about the following network modules for Cisco modular
routers:
• 1-port channelized E1/ISDN PRI balanced (120-ohm) network module—(Cisco
product number NM-1CE1B or CPANM-1CE1B). (See Figure 8-11.) This module is
also referred to as the 1-port CE1/PRI-B network module.
• 2-port channelized E1/ISDN PRI balanced (120-ohm) network module—(Cisco
product number NM-2CE1B or CPANM-2CE1B). (See Figure 8-12.) This module is
also referred to as the 2-port CE1/PRI-B network module.
