the individual card reference section for more information about software limitations for this card.

3.2 EC1-12 Card

For hardware specifications, see the

The EC1-12 card provides 12 Telcordia-compliant, GR-253 STS-1 electrical ports per card. Each port

operates at 51.840 Mbps over a single 75-ohm, 728A or equivalent coaxial span.

STS path selection for UNEQ-P, AIS-P, and bit error rate (BER) thresholds is done on the SONET ring

interfaces (optical cards) in conjunction with the STS cross-connect. The EC1-12 terminates but does

not select the 12 working STS-1 signals from the backplane. The EC1-12 maps each of the 12 received

EC1 signals into 12 STS-1s with visibility into the SONET path overhead.

An EC1-12 card can be 1:1 protected with another EC1-12 card but cannot protect more than one EC1-12

card. You must install the EC1-12 in an even-numbered slot to serve as a working card and in an

odd-numbered slot to serve as a protect card.
