TEI Assignment
Problem:
The TE cannot initialize TEI
Solution:
Ensure that the physical interface is synchronized.
Solution:
If fixed TEIs (values between1-63) are used, ensure that a
different value is used for each TE at both ports (Note: a TEI
value of 0 is not supported).
Solution:
If the TE permits use of dynamic TEIs, this option is strongly
recommended.
Solution:
Ensure that no more than 2 TEI's are being initialized for either
SAPI 0 or SAPI 16 at each port.
Problem:
The TE indicates that TEIs are periodically
removed.
Solution:
Ensure that duplicate fixed TEIs are not assigned to any device
connected to the ILS-2000.
Solution:
TEI removal is normal whenever an interface first synchronizes.
Solution:
Ensure that no more than 2 TEI's are being initialized for either
SAPI 0 or SAPI 16 at each port.
Problem:
My CPE device requires a TID to operate
Solution:
Program the device's SPID with the first 8 digits of the port's
SPID, and then use the last 2 digits of the port's SPID for the
device's TID.
Example:
For a CPE device connected to port 1, which requires a TID to
operate, program the SPID as 08358661 and the TID as 01.
Call Control
Problem:
Caller ID doesn’t work.
Solution:
Ensure that the Caller Identification setting is enabled.
Solution:
Ensure that the Directory Number is programmed into the TEI
(when required by the TE manufacturer.)
Solution:
If the TE has a caller presentation option which permits disabling
Caller ID, do not disable this option.
Solution
: Some TEs do not permit Caller ID.
