Adtran 1184533L3E OPTI-6100 DS3M3T IEEE 1613

Maps/demaps three DS3s or EC1s to/from three STS-1s. Optional equipment protection with redundant (1:1) modules. Optional Auto In-Service Timer. On-board frame circuitry. Hot swap capability. Three DS3 or EC1 interfaces; Mixed DS3/EC1 operation not supported. STS-1 path protection path termination performance monitoring alarm surveillance and provisioning. Meets GR-253 and GR-499 transmit and receive jitter requirements. Provisionable DS3 transmit level (Short/Long). Supports B3ZS coding for DS3 and EC1. Automatic Receive Equalization DS3 framing format detection FEAC loopback code detection and performance monitoring. Monitors receive signal for Loss Of Signal (LOS) Loss of Framing (LOF) and Line Code Violations (LCVs). Centrally managed by the System Controller Module (SCM P/N 1184500L1E). EC1 mode supports the following additional features: -Three SONET DCCs to the SCM via the OMM -Can provide system timing -EC1 Tx/Rx are retimed to the system clock.
