Each of the T1 network module versions supports speeds of up to 1.544Mbps full duplex and provides up to 24
virtual interfaces in channelized mode and up to 23 ISDN b-channels in the PRI mode. The E1 network modules
come in either balanced (120 ohm) or unbalanced (75 ohm) modes and are compatible with the ITU-T G.703/G.704
specifications. The E1 network modules support speeds of up to 2.048-Mbps full duplex and provide up to 30 virtual
interfaces in channelized mode and up to 31 ISDN b-channels in PRI mode.

3640 Applications with Mixed Media Network Modules
These network modules enable the following applications:
• Low-end Hybrid Access Server—The 3620 can support up to four ISDN/PRI or Channelized T1/E1 interfaces
with a single-port 10/100BaseTX interface or can support up to two ISDN/PRI or Channelized T1/E1 interfaces,
with up to 30 digital modems with a single 10/100BaseTX interface.
• Increased Network Module slot utilization—The 3640 supports up to eight Channelized or ISDN/PRI T1/E1
interfaces for up to 240 simultaneous remote connections.
• Expanded versatility—The 3640 offers two ISDN/PRI interfaces with up to 60 digital modems and has an
available slot for other uses, such as VoIP, ATM, hardware compression, HSSI, and WAN backhaul capabilities.
• Integrated CSUs for more efficient management, and both space and cost savings
• RJ-45 connector to attach to Category 5 unshielded twisted-pair (UTP; for example, 10 or 100BaseTX)
• Support for Inter-Switch Link (ISL) over Fast Ethernet to ensure compatibility with the Catalyst
Catalyst 5500, and Catalyst 3000 switches
• Conform with the IEEE 802.1Q Fast Ethernet specification, ensuring multivendor interoperability
• 10 or 100BaseTX operation, autosense, and autonegotiation support
• Full, and half-duplex operation
