Symptom What to do
There is no dial tone when
pressing either the host calling or
local calling keys. 1 Check the IP network to ensure the
following:
!
The IP network is not down.
!
Traffic is being routed between the
Digital Telephone IP Adapter unit and
RLC on the host PBX.
2 Contact your telecom administrator.
There might be problems at the host
PBX.
A stutter is heard during a remote
dial tone. This is a normal occurrence and is caused
by the DSP activating a dial tone relay.
However, to eliminate stutter dial tone,
disable Dialtone Relay. Dialtone Relay
settings are in the Advanced Configuration
dialog box, which is available on the RLC
System Configuration Property sheet.
Lamps or indicators are not lit
after completion of a Digital
Telephone IP Adapter unit power
cycle. 1 Check all cable connections to and from
the Digital Telephone IP Adapter unit to
ensure that they are all securely
connected.
2 Check the IP network and ensure that:
!
it is not down
!
traffic is being routed between the
Digital Telephone IP Adapter unit and
RLC on the host PBX
3 PING the RLC from the Digital
Telephone IP Adapter unit to verify IP
network connectivity.
Lamps or indicators do not reflect
the true status of the telephone. It is possible that there is a synchronization
error between the Digital Telephone IP
Adapter unit and the host PBX. Contact
your telecom network administrator.
