Line Pool Access Code Gets Busy Tone - Nortel ICS Install Manual

Line pool access code gets busy tone

Possible problem
There are not enough lines in the line pool to serve the number
of users.
Solution
If the line pool contains loop start trunks, enter programming
and move under-used loop start trunks from other line pools
into the deficient line pool.
OR
If the line pool contains E&M trunks, order more trunks from
the telephone company or private network vendor. Install
additional E&M Trunk Cartridges. In programming, add the
new trunks to the deficient line pool.
OR
Create a separate line pool for remote users only.
Possible problem
There are DID lines in the line pool.
Solution
In programming, make sure that there are no DID lines in any
of the line pools.
