Mocomtech CRS-300 operation manual 3.2 G.703 Balanced / Unbalanced Data Connections

CRS-300 1:10 Redundancy Switch	Revision 16
Cables and Connections	MN/CRS300.IOM

For specific details regarding the CA/WR0066 cable’s use as a TMI control and/or data cable, refer to the data connection cabling instructions that follow for each driving traffic data type.

Additionally, when either the CRS-316, CRS-325, or CRS-336 TMI is used, the CA-0000069 (HD-15M to DB-9M, 6’) Control Cable is required between the installed TMI(s) and Traffic CDM-625(s).

Refer to Table 4-1in Sect. 4.5.3 and to the data connection cabling instructions that follow for this cable’s required use with the pertinent driving traffic data type.

4.5.3.2G.703 Balanced / Unbalanced Data Connections

If G.703 (Balanced/Unbalanced) is the driving traffic data type, the means of interconnection are dependant on the TMI used. Figure 4-10illustrates use of the CRS-330 and CRS-340 TMIs with G.703, while Figure 4-11illustrates use of the CRS-325 TMI with G.703.

TMIs used for G.703 traffic are not compatible with the CRS-365D TMI used for Quad E1 traffic when used within the same CRS-300.

IMPORTANT

Make all connections according to the information that follows:

►When using the CRS-330 or CRS-340 TMIs (as shown in Figure 4-10):

First, connect the Control/Data Cable CA/WR0066 (for control purposes) between the Redundant CDM-625 and the RMI (see Sect. 4.5.3.1).

Next, connect and secure the Control/Data Cable CA/WR0066 (for control purposes) between the TMI(s) and Traffic CDM-625(s) as follows:

•DB-25M connector labeled “P1” on the TMI(s), to

•DB-25F connector labeled “Data Interface” on the Traffic CDM-625(s).

Finally, connect and secure the Data Cable CA-0000072 (DB-15F to DB-9M, 6’), used for either Balanced or Unbalanced G.703 data, between the RMI or TMI(s) and the Redundant and Traffic CDM-625(s) as follows:

•DB-15M connector labeled “P2” on the RMI or TMI(s), to

•DB-9F connector labeled “Balanced G.703” on the Redundant and Traffic CDM-625(s).

►When using a CRS-325 TMI (as shown in Figure 4-11): Specific cabling requirements apply for operation with the CDM-625.

First, connect the Control/Data Cable CA/WR0066 (for control purposes) between the Redundant CDM-625 and the RMI (see Sect. 4.5.3.1).

Next, connect and secure the Data Cable CA-0000072 (DB-15F to DB-9M, 6’), between the Redundant CDM-625 and RMI as follows:

•DB-9F connector labeled “Balanced G.703” on the Redundant CDM-625, to

•DB-15M connector labeled “P2” on the RMI.

Then, connect and secure the Control Cable CA-0000069 (HD-15M to DB-9M, 6’) between the TMI(s) and Traffic CDM-625(s) as follows:

•HD-15F connector labeled “J1” on the TMI(s), to
