Assign CIC to D-
Channel
If set to yes, D-channel will be assigned with a CIC. Else, D-channel will not be assigned with a CIC. By default, it is set to No
Network
Indicator
Network Indicator (NI) should match in nodes, otherwise, it might cause issues. Users can select “National”, “National Spare”
“International”, or “International Spare”. Usually, “National” or “International” is used.
LBO
The line build-out (LBO) is the distance between the operators and the gateway. Please use the default value of 0dB unless t
distance is long.
Coding
T1: “AMI” or “B8ZS”
E1: “AMI” or “HDB3”
RX Gain Configure the RX gain for the receiving channel of the digital port. The valid range is from -24dB to +12dB.
TX Gain Configure the TX Gain for the transmitting channel of the 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.
Framing Select “esf” or “d4”. The default setting is esf.

Table 29: Digital Hardware Configuration Parameters: T1/J1 – SS7
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 en
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 synchro
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 sla
you.
Slave: The equipment at the far end of the E1/T1 link is the preferred source of the master clock.
Signaling Chooses the signaling protocol that will be used on the digital port.
Coding T1: “AMI” or “B8ZS”
