4-22 Configuring IPmux-8/16 for Operation IPmux-8/16 Ver. 6.00
 Loopback State (Controls activation of diagnostic loopbacks, see Diagnostic
Loopbacks in Chapter 6 for detailed loopback function explanation)
 Internal (Internal loopback is activated)
 External (External loopback is activated)
 Disable (All loopbacks are deactivated)
 Transmit Clock Source
 Adaptive (The internal T1 clock is regenerated from the
IP/Ethernet/MPLS network)
 Loopback (The internal T1 clock is locked on the internal T1 clock
arriving from the T3 device)
 Internal (The internal T1 clock is generated by IPmux-16)
 External (The internal T1 CLK is locked on the external clock port input
signal)
 Port (The T1 clock is regenerated from the IP/ETH/MPLS network. This
option is used to configure more than one internal T1 to adaptive clock.
When the Port clock source is selected, IPmux-16 displays additional
option – Internal T1 Source.)
 Internal T1 Source (To enable the adaptive clock for the current T1 port,
enter the number of the internal T1, which is already configured to the
adaptive clock source.)
• Adaptive mode can be configured for a single internal T1, the rest of the
adaptive ports must be set as Port mode.
• Although configuration requires indicating the internalT1 number, which is set to
adaptive clock, every internal T1 set to the port mode uses its own independent
adaptive clock.
• It is important to maintain T1 clock integrity end-to-end.
