APPENDIX B

TYPICAL CONFIGURATION

Typical conﬁguration is a head-end WAN aggregation point for up to 28 T1s into a single WAN physical interface. The HSIM-W87 can uplink any combination of single T1s or multiple T1 IMUX groups to the backbone. The HSIM-W87 has an internal M13, and the Telco side M13, as shown in Figure B-1, is supplied for CPE aggregation. The HSIM-W84 in the diagram can be any device that is compatible with the HSIM-W87, which runs HDLC WAN protocol.

NOTE

In Figure B-1, the 2E42-27 is used as an example platform. It could be any platform into which the HSIM-W87 can be installed.
