MICRO T1 CSU/DSU
4. Installation
The Micro T1 CSU/DSU is equipped with a DTE, network, and power interface.
This section briefly describes connection to each.
4.1 DTE Interface Connection
The DTE interface is a V.35 DCE presented as an M/34 male connector. This
interface is designed to plug directly into a DTE interface. (See
Appendix B
for
V.35 interface pin assignments.)
4.2 Network Interface Connection
The Network Line Interface is an eight-position keyed modular RJ-48C jack. This
interface will need to be configured to match the line parameters (that is, framing
and line coding) supplied by the Central Office.
NOTE
If the Micro T1 CSU/DSU is being used for private short-range modem
applications, the twisted-pair cable connected to its port will need to be
a crossover cable. See
Appendix B
for interface pin assignments.
4.3 Power Connection
The Micro T1 CSU/DSU is powered via a supplied external transformer, which
connects to the barrel jack on the rear of the Micro T1 CSU/DSU. The Micro T1
CSU/DSU can also be powered via the DTE interface when supplied with 5 VDC @
300 mA to Pin KK. See
Appendix C
for more information.
