Clock Synchronization
For E1:
Term
: Provides an input that terminates the E1 signal.
Monitor
: Provides high-input impedance and compensation for
resistive loss. This setting is useful for monitoring E1 signals at monitor
points, which are resistor-isolated.
Bridge
: Provides high-input impedance for bridging lines that are
already terminated. This setting is useful for bridging directly across
copper cable pairs.
³
Line Coding
: Allows the selection of the interface line coding. Line
Coding is not available with 2 MHz interface. Choices are:
For DS1
:
AMI
and
B8ZS
. The default setting is
B8ZS
.
For E1
:
AMI
and
HDB3
. The default setting is
HDB3
.
³
Framing
: Allows the selection of the interface framing. Framing is not
available with 2 MHz interface. Choices are:
For DS1
:
SF
, and
ESF
. The default setting is
SF
.
For E1
:
PCM30
,
PCM30 CRC-4
,
PCM31
, and
PCM31 CRC-4
. The default
setting is
PCM30
.
