TIM510 E1/T1 Telephony Interface Module
The TIM510 E1/T1 Telephony Interface Module (Figure 43 on page 74), also known
as the TIM510 E1/T1 media module, terminates an E1 or T1 trunk. The TIM510 T1/E1
media module has a built-in channel service unit (CSU) so an external CSU is not
necessary. The CSU is used for a T1 circuit only. Up to two TIM510s can be installed
in any of the slots on the Services Router.

a T1 port.
■ DS1-level support for a variety of E1 and T1 trunk types
■ Trunk signaling to support U.S. and international central office (CO) or tie trunks
■ Echo cancellation in either direction—incoming or outgoing
