STM-1e/EC-3 (155.520 Mb/s) J2914A
General
This electrical interface comprises a plug-in module (J2914A) suitable for
plugging into the J2300C/D/E Agilent Advisor mainframe and J2900A High
Speed undercradle. The interface handles ATM and Packet over SONET/SDH
(PoS).
Common to Inputs and Outputs:
Connectors: 75 Ohm BNC, unbalanced
Electrical: ITU-T G.703
Line Code: CMI
Framing:
SDH: STM-1
SONET: STS-3c
SONET/SDH Frame Scrambling (x 7 + x 6 + 1):
SDH: STM-1, ITU-T G.707
SONET: STS-3c, GR-253
ATM Cell Scrambling: conforms to ITU-T I.432.1 (x 43 + 1) and may be turned on
or off
PoS analysis configurations supported:
IETF PPP in HDLC: RFC 1662 and both current RFC 2615 (x 43 + 1
scrambled SONET/SDH payload) and obsolete RFC 1619 (unscrambled
SONET/SDH payload) versions with version auto-detect based on POH
C2 byte value (default) and manual over-ride for scrambling enable/disable
Cisco HDLC over SONET/SDH
FCS-16 (default) and FCS-32
Inputs:
