Features and functions

DS-3

• Full- and half-duplex connectivity at DS-3 rate (44.736 MHz)

• Scrambling and subrate support of major data-service-unit (DSU) vendors

• C-bit or M23 framing (software selectable)

• MDL

• Support for 16- and 32-bit cyclic redundancy check (CRC) (16-bit default)

• 24-hour history maintained for error statistics and failure counts

• DS-3 alarm and event detection (once-per-second polling)

• Alarm indication signal (AIS)

• Out of frame (OOF)

• Far-end receive failure (FERF)

DS-1

• Superframe (SF) and Extended Superframe (ESF) support

• ANSI T1.403 FDL support

• Internal or line-derived (loop) clocking, independently selectable on each T1 tributary

• Error and alarm detection: CRC errors, framing errors, loss of frame (red), AIS (blue), remote alarm indication (yellow)

• Alarm reporting: 24-hour history maintained, 15-minute intervals on all errors

• BERT at T1 level

• Loopback capabilities: local, network line and network payload, remote network line, and remote network payload at the T1 level

SONET errors, alarms, and performance monitoring

Synchronization:

• Local (internal) or loop timed (recovered from network)

• Pointer activity monitoring

• Redundant clock source should be provisioned on different SPAs as only a single timing source can be provided by SPA

Local (diagnostic) and line (network) loopback

Payload mapping

• POS with 1 + X^43 self-synchronous scrambler

SONET/SDH compliance:
