Chapter 25 CE-1000-4 Ethernet Operation
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
Display of POS Port Provisioning Status” task on page 2-3
. 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
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
