You need a DSU/CSU (digital service unit/channel service unit) between the WAN connection and the gateway. You can order a V.35 or X.21 cable from Nortel to attach to the connector. This cable enables the WAN adapter to function as DTE (data terminal equipment).

Table 26 provides the V.35 cable pinouts. Table 27 on page 59 provides the X.21 cable pinouts. (The pair suffix A or B refers to an individual wire within a twisted pair.)
