plugs into J1 on the modem. Notify your telephone company that the
jack (connector) required for your device is one of the following:
o USOC: RJ11C or
o USOC: RJ11W
: The jack provided on the Modem (J1) is a 6-pin TELCO RJ-

11. The connections to the modem are pin 3 PSTN-Tip, and
pin 4 PSTN-Ring.
 After the telephone company has installed the above jack, connect
the modem to your equipment by inserting the appropriate
equipment interface RJ11 plug into the modem and wall connector.
Bezels are blue plastic covers (see Figure 2-37) that protect an adjacent
pair of I/O modules and provide an easy way for you to route wiring.
The factory provides bezels with each order. Install bezels over I/O
modules whenever the ControlWave EFM is operational; remove the
bezels for maintenance procedures.
Bezels attach to the module covers of two adjacent I/O modules. Hooks
on the bezels (see Figure 2-37) attach to notches in the upper and lower
portions of the module covers. Align the hooks on the bezel with the
notches on the I/O module covers and slide the bezel down. To remove
the bezel, grasp its sides and gently squeeze them, and pull up and then
away from the I/O modules.
