CE-1000-4 Loopback, J1 Path Trace, and SONET/SDH Alarms
The user can provision framing on the CE-1000-4 as either the default frame-mapped generic framing
procedure framing (GFP-F) or high-level data link control (HDLC) framing.
With GFP-F framing, the user can also configure a 32-bit CRC (default) or no CRC (none). When LEX
is used over GFP-F it is standard Mapped Ethernet over GFP-F according to ITU-T G.7041.
HDLC framing provides a set 32-bit CRC.On CTC go to CE card view and click the Provisioning >pos
ports tab, to see the various parameters that can be configured on the POS ports, see “CTC Display of
POS Port Provisioning Status”. Various parameters like, admin state, service state, framing type, CRC
, MTU and soak time for a port can be configured here
For more details about the interoperability of ONS Ethernet cards, including information on
encapsulation, framing, and CRC, see the “POS on ONS Ethernet Cards” chapter.
CE-1000-4 Loopback, J1 Path Trace, and SONET/SDH Alarms
The CE-1000-4 card supports terminal and facility loopbacks. It also reports SONET/SDH alarms and
transmits and monitors the J1 Path Trace byte in the same manner as OC-N cards. Support for path
termination functions include:
•
H1 and H2 concatenation indication
•
Bit interleaved parity 3 (BIP-3) generation
•
G1 path status indication
•
C2 path signal label (read only)
•
Path level alarms and conditions, including loss of pointer (LOP), unequipped, payload mismatch,
alarm indication signal (AIS) detection, and remote defect indication (RDI)
•
J1 path trace for high-order circuit paths
•
Extended signal label for the low-order paths
