The following notes apply to the Single V.35 WAN Interface:

•You will need a DSU/CSU (digital service unit/channel service unit) between the WAN connection and the Switch.

•At each end, Cable shield and connector shell must connect respectively to pin A of 34-pin connector and pin 1 of the standard 28-pin connector.

•The term “no conn” means the wire is not connected to a pin in the 34-pin connector.

•Wires 12B, 13A, and 14B connect to pin B in the 34-pin connector.

•Unused pins in the 34-pin connector need not be present.

•Do not connect Shield to Signal Ground as these are separate signals.

•The pair suffix A or B refers to an individual wire within a twisted pair.
