150CHAPTER 4: CONFIGURING PATHBUILDER S330/S310 MODULES, PORTS, AND APPLICATIONS

For the purposes of this example, assume you want to make the following connections:

■Connect subchannels 1-4 on PBX-1 to subchannels 1-4 on PBX-2

■Connect subchannels 5-8 on PBX-1 to subchannels 1-4 on PBX-3.

You need to build the following VCM VCC and subchannel circuits:

At PathBuilder S330 A (S330 A):

■Add a virtual circuit (VC 1) between S330 A and S330 B.

■Add a virtual circuit (VC 2) between S330 A and S330 C.

■Add four subchannel circuits to VC 1, setting the VCM circuit parameters as follows:

■DS0: 1-4

■DLCI:16

■SCID: 11-14

■Add four subchannel circuits to VC 2, setting the VCM circuit parameters as follows:

■DS0: 5-8

■DLCI:17

■SCID: 11-14

At PathBuilder S330 B (S330 B):

■Add a virtual circuit (VC 1) between S330 B and S330 A.

■Add four subchannel circuits to VC 1, setting the VCM circuit parameters as follows:

■DS0: 1-4

■DLCI:16

■SCID: 11-14

At PathBuilder S330 C (S330 C):

■Add a virtual circuit (VC 2) between S330 C and S330 A.

■Add four subchannel circuits to VC 2, setting the VCM circuit parameters as follows:

■DS0: 1-4

■DLCI:17

■SCID: 11-14
