THEN What to do
Contact your network administrator to
conduct a traffic study on your voice and IP
network traffic patterns as described in the
Remote Office Network Engineering
Guidelines (NTP 555-8421-103). (This NTP
is available from your Nortel Networks
distributor.) It is possible that your IP
network capacity cannot accommodate the
additional voice data, especially during
High Day Busy Hour (HDBH) periods.
Make adjustments to your network as
required.
1 Ensure your telephone is not on call
forward.
2 Ensure that the Meridian Digital
Telephone IP Adapter unit is not in
offline mode by entering the online
SPRE code at a digital telephone.
3 Ensure that the Meridian Digital
Telephone IP Adapter unit is powered
up. It cannot receive calls from the host
PBX if it is not powered up.
4 The network administrator should
ensure the RLC is correctly configured
with your Meridian Digital Telephone IP
Adapter unit's IP address, telephone
number, and security ID (if they are
used).
