Basic Settings
Clock
All E1/T1/J1 spans generate a clock signal on their transmit side. The parameter determines whether the clock signal from
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 syste
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
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.
The user can group multiple E1 lines with a single data channel.
LBO
The line build-out (LBO) is the distance between the operators and the gateway. Please use the default value of 0dB unles
distance is long.

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.
