4.4 CONNECTING THE NETWORK AND THE V.35 INTERFACES
Figure 4, below, shows the position of the RJ-48C network and V.35
connector on the rear of the
Model 1000RCM13448C
panel.
4.4.1 Network Interface Connection
The Network Line Interface is an eight position keyed modular jack
configured as a RJ-48C. This interface will need to be configured to
match the line parameters (i.e. framing, line coding, etc.) supplied by
the central office.
5.0 OPERATION
Once you have configured each Model 2715RC and connected the
cables, you are ready to operate the units. Section 5.0 describes the
power-up procedure, LED status indicators and the built-in loopback
test modes.
5.1 POWER-UP
There is no power switch on the Model 2715RC: Power is automat-
ically applied to the Model 2715RC when its card-edge connector
makes contact with the chassis’ mid-plane socket, and when the chas-
sis’ power supply is turned on.
Note: The Model 2715RC is a “hot
swappable” card—it will not be damaged by plugging it in or removing
it while the rack is powered up.
5.2 LED STATUS MONITORS
The Model 2715RC features four front panel LEDs that monitor
and power, data, alarm and testing conditions. Figure 8 (below) shows
the front panel location of each LED. Following Figure 8 is a descrip-
tion of each LED’s function.
TXD
When the unit sends a one, the green TXD LED
is turned on. When it sends a zero, the yellow
TXD LED is turned on.
RXD
When the unit receives a one, the green RXD
LED is turned on. When it receives a zero, the
yellow RXD LED is turned on.

Notice!
Any modular twisted pair cable connected to
the rear card must be shielded cable, and the outer shield
must be properly terminated to a shielded modular plug
on both ends of the cable.
