Note The DS1/E1-56 card supports an errorless software-initiated cross-connect card switch when used in a
shelf equipped with XC-VXC-10G and TCC2/TCC2P cards.
You can install the DS1/E1-56 card in Slots 1 to 3 or 15 to 17 on the ONS 15454, but installing this card
in certain slots will block the use of other slots. Table 3-6 shows which slots become unusable for other
electrical cards when the DS1/E1-56 card is installed in a particular slot.
With the proper backplane EIA, the card supports SCSI (UBIC) connectors. See the “7.2 Elec trical Card
Protection and the Backplane” section on page 7-5 for more information about electrical card slot
protection and restrictions.
Connectivity, error rate, and error count of the traffic running on an Electrical IO card ports can be tested
by using BERT. For more information on BERT, see 3.2 Bit Error Rate Testing, page 3-4.
