CISCO 2600/3600/3700 ISDN PRI CONNECTIVITY OPTIONS
(NM-1CT1, NM-1CT1-CSU, NM-2CT1, NM-2CT1-CSU, NM-1CE1B, NM-2CE1B, NM-1CE1U, NM-2CE1U, NM-1FE1CT1, NM-

The astonishing versatility of the Cisco 2600, 3600 and 3700 router series is highlighted by its broad support of Integrated
Services Digital Network Primary Rate Interface (ISDN PRI) connectivity.
The available Cisco 2600/3600/3700 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 2600/3600/3700 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 and 3700 Series only supports PRI network modules without a LAN connection.
Note: The 3631 Series is not supported.
For midrange, high-density ISDN PRI applications, the Cisco 2600/3600/3700 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 and 3700 internal digital modems in the 3600 and 3700 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.
