 Product
Description: Cisco 2691, 2800, 3600, 3700, 3800
Series -
1-Port T3/E3 network module. The Cisco T3/E3 network module provides
direct connectivity to a T3 line for full-duplex communications
at the T3 rate of 44.736 MHz and full-duplex E3 communications
at 34.368 MHz. Each T3 or E3 port consists of a pair of 75-ohm
BNC coaxial connectors (Type RG-59), one for transmit data and
one for receive data, along with six LED indicators for line
status. The Cisco 2650XM and 51XM, Cisco 2691, Cisco 3660, and
the Cisco 3725 support a single T3/E3 network module. The Cisco
3745 supports up to two single-port Cisco T3/E3 network modules.
Because the Cisco T3/E3 network module is supported in Cisco IOS
feature sets, there are no additional memory
requirements for any supported platforms.
