description of each card.

2.2.1 Common Control Cards

This section describes the common control cards (TCC2, TCC2P, AIC-I, and MS-ISC-100T).

2.2.1.1 TCC2 Card

The Advanced Timing, Communications, and Control (TCC2) card performs system initialization,
provisioning, alarm reporting, maintenance, diagnostics, IP address detection/resolution, SONET
section overhead (SOH) data communications channel/generic communications channel (DCC/GCC)
termination, optical service channel (OSC) DWDM data communications network (DCN) termination,
and system faultdetection for the ONS 15454. The TCC2 also ensures that the system maintains Stratum
3 (Telcordia GR-253-CORE) timing requirements. It monitors the supply voltage of the system.
Figure 2-1 shows the faceplate and block diagram for the TCC2.
MXP_MR_10DME_C 15454-10DME-C= The MXP_MR_10DME_C and MXP_MR_10DME_L cards
aggregate a mix of client SAN service client inputs (GE, FICON, and
Fibre Channel) into one 10-Gbps STM-64/OC-192 DWDM signal on
the trunk side. It provides one long-reach STM-64/OC-192 port per
card and is compliant with Telcordia GR-253-CORE and ITU-T
G.957. They pass all SONET/SDH overhead bytes transparently.
The ITU-T G.709 compliant digital wrapper function formats the
DWDM wavelength so that it can be used to set up generic
communications channels (GCCs) for data communications, enable
forward error correction (FEC), or facilitate performance monitoring
(PM). The cards work with the OTNdevices defined in ITU-T G.709.
The cards support ODU1 to OTU2multiplexing, an industry standard
method for asynchronously mapping a SONET/SDH payload into a
digitally wrapped envelope. You can install MXP_MR_10DME_C
and MXP_MR_10DME_L cards in Slots 1 to 6 and 12 to 17.
The MXP_MR_10DME_C card features a tunable 1550-nm C-band
laser on the trunk port. The laser is tunable across 82 wavelengths on
the ITU grid with 50-GHz spacing between wavelengths. The
MXP_MR_10DME_Lfeatures a tunable 1580-nm L-band laser on the
trunkport. The laser is tunable across 80 wavelengths on the ITU grid,
also with 50-GHz spacing. Each card features four 1310-nm lasers on
the client ports and contains fivetransmit and receive connector pairs
(labeled) on the card faceplate. The cards use dual LC connectors on
the trunk side and use SFP modules on the client side for optical cable
termination. The SFP pluggable modules are SR or IR and support an
LC fiber connector.
