Table 4-1. Cabling Procedure

StepProcedure

Follow channel device guidelines regarding RS232 cable lengths and make sure that the pin assignment in Appendices B and C of this manual are followed.

Voice/Fax Channels

3If the Voice/fax board is being connected to the trunk side of a PBX, connect the E&M (I-V) Voice/fax Channel cable supplied with your MultiMux between the VOICE/FAX CHANNEL 1 or 2 E&M connector on the back panel of the MultiMux and the PBX. Configuration 5 (E&M I-V) and configuration 7 (E&M I-V to FXS) are examples of E&M connections and are described in Chapter 2 of this manual.

Connect the RJ45 connector of this cable to either VOICE/FAX CHANNEL 1 E&M connector on the back panel of the MultiMux or to VOICE/FAX CHANNEL 2 E&M connector on the MultiMux. Pin assignments for this cable are described in Appendix D.

Connect the spade lug end of this cable to the trunk side of the PBX. Refer to the PBX manual for this connection.

Note

If the spade lugs are not needed on the PBX

end, they may be cut off the cable.

4If the Voice/fax board is being connected to the station side of a PBX, connect an RJ11 phone cable between the VOICE/FAX CHANNEL 1 or 2 FXO connector on the back panel of the MultiMux and to the station side of the PBX. Configuration 4 (FXO to FXS) is a example of this connection and is described in Chapter 2 of this manual. Refer to the PBX manual for the station side connection.

5If the Voice/fax board is being connected to a station instrument (telephone, KTS-key telephone system, or fax machine), connect one end of an RJ11 phone cable to either the VOICE/FAX CHANNEL 1 or 2 FXS connector on the back panel of the MultiMux and the other end to the station instrument. Configuration 6 (FXS to FXS) is an example of this connection and is described in Chapter 2 of this manual.

6 Perform the configuration procedures in Table 4-3.
