Table 25: 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 gateway system clock will synchronize to it.
• Master:
The port will never be used as a source of timing. This is
appropriate when you know 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.
Signaling
Chooses the signaling protocol that will be used on the digital port.
PRI: when one end is set to NET, the other end should be set to CPE
Data channel
Chooses the Data Channel for control.
LBO
The line build-
out (LBO) is the distance between the operators and the
gateway. Please use the default value 0dB unless the distance is long.
Coding
T1:"AMI" or "B8ZS"
E1:"AMI" or "HDB3"
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.
