13 Disconnect the modem from the workstation.
14 Ensure that the modem at the NAC site is properly connected and
powered up.
The NAC initiates the signal that connects the modems.
The Meridian MAX modem dials the NAC telephone number as
recorded during step 8.
The connection between the NAC site and the Meridian MAX site is
confirmed when the carrier detect (CD) LED remains constantly on.
15 For an SNN/SNN-E, connect the modem directly to the Meridian MAX
multiport cable using an NT7D99AA modem cable.
For an IPE/IPE-E, connect the modem directly to the Meridian MAX
multiport cable using an NT1R03HF modem cable.
Ensure that the modem is connected to the telephone system with an
RJ-11 cable/connector.
16 Power up the modem.
If your Meridian MAX system is powered up and functional, the LED
labeled “TR” will light up on the front panel of the modem. If the “TR”
LED does not light up, repeat this procedure. If the light still does not
appear, contact your Nortel representative.
