3.2 3.1.2 Card Compatibility

3.1.2 Card Compatibility

Table 3-2 lists the CTC software compatibility for each electrical card. See Table 2-4 on page 2-4 for a

list of cross-connect cards that are compatible with each electrical card.

Note “Yes” indicates that this card is fully or partially supported by the indicated software release. Refer to

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

3.2 EC1-12 Card

Note For hardware specifications, see the “A.5.1 EC1-12 Card Specifications” section on page A-15.

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.
