CTP151 T1/E1 Interface Module

 

The Juniper Networks CTP151 Circuit to Packet platform optionally includes a replaceable CTP150-IM-T1E1 interface module that can be paired with another module of the same type or a serial interface module.

The four-port T1/E1 interface module supports individual cabling for each port. The CTP151 ports have T1/E1 ports for RJ-48 connectors (see Figure 1). The highest-numbered port (labeled 3) is on the left, and the lowest-numbered port (labeled 0) is at the right, with the CLK port still farther to the right.

The software-selectable T1/E1 interfaces for the module are T1, E1, fractional T1, and fractional E1. CSU options, encoding, and encapsulation are also software-selectable.

The module also includes an external clock reference port for an RJ-48 connector.

Note

The external clock reference port must be used only on the module in slot 0, the left-most slot on the front of the CTP151 chassis. For information about the CTP151 modules slot numbering, see CTP151 Modules Slot and Port Numbering.
