Figure 46: Digital Port Configuration
The GXW450X currently supports E1, T1, and J1 digital hardware types. When different signaling is selected for E1, T1, or J1, the settings in basic o
and advanced options will be different. The following tables list all the settings to configure digital ports when selecting each signaling.
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.
