The available Cisco 3600/2600 PRI network modules
provide various port densities to meet customer requirements
at various price points. The optional, integrated CSU lets
customers consolidate customer premises equipment (CPE)
to provide multifunction dial access server, router, and other
capabilities within the Cisco 3600/2600 series in power
branch office environments. The balanced and unbalanced
serial connectivity options enable conformity to a customer’s
specific application.
Customers can choose among a number of network
module options to precisely fit their requirements:
• NM-1CT1—One-port Channelized T1/ISDN PRI
• NM-1CT1-CSU—One-port Channelized T1/ISDN PRI
with Channel Service Unit (CSU)
• NM-2CT1—Two-port Channelized T1/ISDN PRI
• NM-2CT1-CSU—Two-port Channelized T1/ISDN PRI
with CSU
• NM-1CE1B—One-port Channelized E1/ISDN PRI,
balanced
• NM-1CE1U—One-port Channelized E1/ISDN PRI,
unbalanced
• NM-2CE1B—Two-port Channelized E1/ISDN PRI,
balanced
• NM-2CE1U—Two-port Channelized E1/ISDN PRI,
unbalanced
• NM-1FE1CT1—One-port 10/100BaseTX Ethernet with
one-port T1 PRI/Channelized
• NM-1FE1CT1-CSU—One-port 10/100BaseTX Ethernet
with one-port T1 PRI/Channelized with integrated CSU
• NM-1FE2CT1—One-port 10/100BaseTX Ethernet with
two-port T1 PRI/Channelized
• NM-1FE2CT1-CSU—One-port 10/100BaseTX Ethernet
with two-port T1 PRI/Channelized with integrated CSU
• NM-1FE1CE1B—One-port 10/100BaseTX Ethernet with
one-port E1 PRI/Channelized Balanced mode (120 ohm)
• NM-1FE1CE1U—One-port 10/100BaseTX Ethernet with
one-port E1 PRI/Channelized Unbalanced mode (75 ohm)
• NM-1FE2CE1B—One-port 10/100BaseTX Ethernet with
two-port E1 PRI/Channelized Balanced mode (120 ohm)
• NM-1FE2CE1U—One-port 10/100BaseTX Ethernet with
two-port E1 PRI/Channelized Unbalanced mode (75 ohm)
Note: The 2600 only supports PRI network modules
without a LAN connection.
For midrange, high-density ISDN PRI applications, the
Cisco 3600/2600 provides superior performance and port
densities. For example, a fully configured Cisco 3640 can
support 8 ISDN PRI ports in one chassis, which can be
multiplexed to provide up to 192 T1 channels at 56/64 kbps
T1, or 240 E1 channels at 56-64 kbps.
These PRI and FE/PRI network modules support the
3600 internal digital modems in the 3600 for PRI, CT1, and
R2 connections. This allows up to 30 V.90 modems in a 3620
or 60 V.90 modems in a 3640.
