- The
120A channel service unit (CSU) module connects to either a TN464E/F
or a TN767D/E DS1 circuit pack on 1 end. The other end connects
to the network interface smart jack. The 120A is powered from
the +5 VDC port carrier power supply and uses a maximum of 1.2
Watts.
- In
combination with the DS1 circuit pack, it provides the essential
functions of external CSUs. The TN464/767 and switch administration
support all framing and line coding options.
- The
120A is small, a little larger than a wallet, is easier to install
than an external CSU, and does not require any option switch settings
or DS1 cable.
- Includes
Clip and Cable.
