Connections of Signal Cables in the GBCR (Configuration Type A)

The signal cables in the GBCR consist of the active/standby 75-ohm coaxial cable, active/standby 120-ohm twisted pair cable, optical cable, straight-through cable,inter-GTNU cable, BITS clock cable, Y-shaped clock cable, and PDB monitoring signal cable.

Figure 1 shows the GBCR configured with the IBM X3650T GBAM.
Figure 2 shows the GBCR configured with the C5210/HP CC3310 GBAM.

NOTE:

Figure 1 and Figure 2 show the connections of signal cables between a GMPS and a GEPS. If there are more than one GEPS, you need to connect each GEPS to the GMPS directly. The connection method is the same as the method of connecting the first GEPS to the GMPS.
The types of interface boards, installation positions of cables, and number of cables shown in Figure 1 and Figure 2 are examples. The actual types of interface boards, installation positions of cables, and number of cables depend on the site plan.

Table 1 describes the connections of the signal cables in the GBCR.
