Designation Function
Values
I TS CODE
Selects the code transmitted to fill
idle (empty) time slots in the frames
transmitted on the T1 or E1 line by
the KML.7 and KML.8 modules.
The available selections are 00 to FF (hexa)
Default: 00 for the KML.7,
3F for the KML.8
FRAME
Selects the multiframing mode for the
KML.7 and KML.8 modules.
KML.7 module:
D4(SF) - 12 frames per multiframe
ESF - 24 frames per multiframe
Default: SF
KML.8 module:
G732N - 2 frames per multiframe
G732S - 16 frames per multiframe
Default: G732N
SYNC
Selects the frame synchronization
algorithm used by the KML.7 and
KML.8 modules, and thus effects the
time required to return to normal
operation after local loss of
synchronization.
CCITT
- Complies with ITU-T Rec. G.732
(on the KML.8 module only)
62411
- As required by AT&T TR-62411
(after 10 seconds)
FAST
- After 1 second
Default: FAST
CRC-4
Enables the generation of check bits
in accordance with the CRC-4
polynomial specified by ITU-T Rec.
G.704 for the frames transmitted on
the E1 line, and the checking of the
check bits carried by the received E1
frames. This parameter is available
only on the KML.8 module.
NO
- CRC-4 option disabled
YES
- CRC-4 option enabled
Default: NO
CODE
Selects the line coding method used
for zero suppression on the T1 link of
the KML.7 module.
TRAN
- Transparent (AMI) coding, no
processing for zero suppression
B7ZS
- B7ZS coding
B8ZS
- B8ZS coding
Note
: Clear channel capability is available
only with B8ZS coding.
Default: B8ZS
FUNCTION
Displays the function of the link
interface of the KML.7 and KML.8
modules.
On KML.7 module only:
DSU
- The module has a DSU link
interface
CSU
- The module has a CSU link
interface
On KML.8 module only:
DSU
- The module has an LTU link
interface
