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.
