Table 51: Digital Hardware Configuration Parameters: T1/J1 - PRI_NET/PRI_CPE
Basic Settings
Clock
All E1/T1/J1 spans generate a clock signal on their transmit side. The
parameter determines whether the clock signal from the far end of the
E1/T1/J1 is used as the master source of clock timing. If the far end is used
as the master, the PBX system clock will synchronize to it.
• Master: The port will never be used as a source of timing. This is
appropriate when you know the far end should always be a slave to
you.
• Slave: The equipment at the far end of the E1/T1/J1 link is the
preferred source of the master clock.
LBO
The line build-out (LBO) is the distance between the operators and the
PBX. Please use the default value 0dB unless the distance is long.
RX Gain
Configure the RX gain for the receiving channel of digital port. The valid
range is from -24dB to +12dB.
TX Gain
Configure the TX Gain for the transmitting channel of digital port. The valid
range is -24dB to +12dB.
Codec Select alaw or ulaw. If set to default, ulaw will be used for T1/J1.
Play Local RBT
This configured whether to play the ringback tone from local UCM6510 or
not. If enabled, the local UCM6510 will play ringback tone to the caller.
