Chapter 7 Card Protection
7.2.3 MiniBNC Protection
7.2.3 MiniBNC Protection
When used with the MiniBNC EIA, the ONS 15454 supports unprotected, 1:1, or 1:N (N
<
5) electrical
card protection for DS-1, DS-3 and EC-1 signals, as outlined in
Table 7-1 on page 7-2
and
Table 7-2 on
page 7-3
. The MiniBNC EIA provides 192 MiniBNC connectors for terminating up to 96 transmit and
96 receive signals per EIA, enabling 384 MiniBNC connectors for terminating up to 192 transmit and
receive signals per shelf with two MiniBNC panels installed. With an A-Side MiniBNC EIA, Slots 1, 2,
4, 5, and 6 can be used for working slots and on a B-Side panel, Slots 12, 13, 14, 16, and 17 can be used
for working slots. Each of these slots is mapped to 24 MiniBNC connectors on the EIA panel to support
up to 12 transmit/receive signals. In addition, working Slots 1, 2, 16 and 17 can be mapped to 96
MiniBNC connectors to support the high-density electrical card. These slots can be used with or without
equipment protection for DS-3 and EC-1 services.
7.2.4 SMB Protection
When used with the SMB EIA, the ONS 15454 supports unprotected, 1:1, or 1:N (N
<
5) electrical card
protection for DS-3 and EC-1 signals, as outlined in
Table 7-1 on page 7-2
and
Table 7-2 on page 7-3
.
The SMB EIA provides 168 SMB connectors for terminating up to 84 transmit and 84 receive signals
per EIA, enabling 336 SMB connectors for terminating up to 168 transmit and receive signals per shelf
with two SMB EIAs installed. With an A-Side SMB EIA, Slots 1, 2, 3, 4, 5, and 6 can be used for
working slots and with a B-Side EIA, Slots 12, 13, 14, 15, 16, and 17 can be used for working slots. Each
of these slots is mapped to 28 SMB connectors on the EIA to support up to 14 transmit/receive signals.
These slots can be used with or without equipment protection for DS-1, DS-3 and EC-1 services. For
DS-1 services, an SMB-to-wire-wrap balun is installed on the SMB ports for termination of the 100 ohm
signal.
7.2.5 AMP Champ Protection
When used with the AMP Champ EIA, the ONS 15454 supports unprotected, 1:1, or 1:N (N
<
5)
electrical card protection for DS-1 signals, as outlined in
Table 7-1 on page 7-2
and
Table 7-2 on
page 7-3
. The AMP Champ EIA provides 6 AMP Champ connectors for terminating up to 84 transmit
and 84 receive signals per EIA, enabling 12 AMP Champ connectors for terminating up to 168 transmit
and receive signals per shelf with two AMP Champ EIAs installed. With an A-Side SMB EIA, Slots 1,
2, 3, 4, 5, and 6 can be used for working slots and with a B-Side EIA, Slots 12, 13, 14, 15, 16, and 17
can be used for working slots. Each of these slots is mapped to 1 AMP Champ connector on the EIA to
support 14 transmit/receive signals. These slots can be used with or without equipment protection for
DS-1 services.
7.2.6 UBIC Protection
When used with the UBIC EIA, the ONS 15454 high-density shelf assembly (15454-HD-SA) supports
unprotected, 1:1, or 1:N (N
<
5) electrical card protection for DS-1, DS-3 and EC-1 signals, as outlined
in
Table 7-1 on page 7-2
and
Table 7-2 on page 7-3
. The UBIC EIA provides 16 SCSI connectors for
terminating up to 112 transmit and receive DS-1 signals per EIA, or up to 96 transmit and receive DS-3
connections. With an A-side UBIC EIA, Slots 1, 2, 3, 4, 5, and 6 can be used for working slots and with
a B-Side EIA, Slots 12, 13, 14, 15, 16, and 17 can be used for working slots. Each of these slots is
mapped to two SCSI connectors on the EIA to support up to 14 transmit/receive signals. In addition,
working Slots 1, 2, 16, and 17 can be mapped to 8 SCSI connectors to support the high-density electrical
card. These slots can be used with or without equipment protection for DS-1, DS-3, and EC-1 services.
