Payload capability
Payload mappings
(to Bellcore GR-253-CORE):
OC-12/OC-12c/OC-3/OC-3c
capability when optical module fitted.
DS3(44.736 Mb/s) into STS-1 SPE and
STS-1 SPE bulk filled mappings:
DS1(1.544Mb/s) async into VT1.5.
139.264 Mb/s into a STS-3c SPE and
STS-3c SPE bulk-filled mappings.
2.048 Mb/s (async and fl. byte sync)
into VT2 SPE and VT2 SPE bulk filled
mappings:
34.368 Mb/s, into STS-1 SPE and STS-
1 SPE bulk filled mappings:
VT6 SPE bulk filled mapping and VT6
-Nc (for N = 2 to 6):
† DS1, DS3 mappings require DSn/
PDH option UKJ, UKN or 110 to be
fitted.
Payload data: The following unframed
patterns can be generated: (Framed and
structured signals are available in
conjunction with the PDH/DSn options
UKJ/UKN/110).
9 11
PRBS: 2 -1 (O.150), 2
15 23
2 -1 (O.151) and 2 -1 (O.151)
20
QRSS (2 -1, 14 zero limited)†
Word: User-defined 16-bit word, all
ones, all zeros, 1010, 1000. All PRBS
patterns can be set to be inverted or
non-inverted.
† Applicable to DS1 mappings only.
Payload framing: 139.264, 34.368 and
2.048 Mb/s: Unframed.
1-28
139.264, 34.368 and 2.048 Mb/s:
Framed and structured signals†
DS3 payloads: Unframed, C-Bit parity
(to ANSI T1.107a-1990)†
M13 (to ANSI T1.107-1988).
VT6: Unframed. DS1 payloads:
Unframed, SF (D4), ESF (to ANSI
T1.403-1989, TR-TSY-000499 and
ITU-T G.704), SLC-96†.
† Only available in conjunction with
the PDH/DSn option UKJ/UKN/110.
Drop/insert: 139.264Mb/s: Drop/insert
via Tx/Rx on options UKJ/UKN.
45.736 (DS3): Drop/insert via Tx/Rx
on option 110.
34.368 Mb/s: Drop/insert via Tx/Rx on
options UKJ/UKN/110.
2.048 Mb/s: Drop/insert via drop/insert
ports on options UKJ/UKN/110.
1.544 Mb/s (DS1): Drop/insert via
drop/insert ports on option 110.
Pointer adjustment generation
Increment/decrement/alternating:
Provides a burst, selectable between 1
and 10 pointer adjustments (between 1
and 5 for VT6, VT2 and VT1.5
pointer).
New pointer value: The STS-3c SPE,
STS-1 SPE, VT6, VT2 or VT1.5 moves
-1 (O.152),
to a selectable new location in a single
jump, with or without an accompanying
new data flag (NDF).
Frequency offset (and 87:3):
Pointer sequences are generated by
offsetting the frequencies of the STS-3c
SPE, STS-1 SPE (in these modes the
87:3 sequence is generated to Bellcore
GR-253-CORE/ANSI T1.105.03) or
VT6, VT2, VT1.5 and the line rate
