CTP151 Serial Interface Module
The Juniper Networks CTP151 Circuit to Packet platform optionally includes a replaceable CTP150–IM-SER
serial interface module that can be paired with another module of the same type or a T1/E1 interface
module. The serial interface module also has the option of supporting two multiservice daughter cards for
4-KHz or high-quality analog audio, or interrange instrumentation group (IRIG) signals. See “CTP151
Multiservice Interface Module” on page 10 for details.
The four-port serial interface module supports individual cabling for each port. The CTP151 ports have
small serial ports for HD-26 26-pin connectors (see Figure 5 on page 9 ). The lowest-numbered port
(marked 0) is at the bottom left, and the highest-numbered port (marked 3) is at the top right.
