TIM510 E1/T1 Telephony Interface Module

The TIM510 E1/T1 Telephony Interface Module (Figure 42 on page 73), 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.

■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
