Restoring Defaults
If your TLS-5 does not operate as expected, a previous user’s feature
programming may be the cause. To restore the unit to default operating
conditions:
·
Be sure all phones are on-hook, then toggle the front panel switch to OFF,
then to MAN/RING and hold
until the POWER LED comes on
, then release.
or:
·
Enter **99## to access programming mode and enter: *00#0#*00#0#
Installing Caller ID Equipment
·
Follow the Caller ID device manufacturer’s instructions, treating the TLS-5
as the telephone line.
Testing Installations
The procedures below assume that the TLS-5 default settings have
not
been
changed. If you have trouble with any of the following procedures, the TLS-5
may already be programmed.
Testing key system and PBX lines
·
Connect the TLS-5 lines to Tip and Ring of PBX or key system central office
loop start trunks (E&M, DID, or ground start trunks
cannot
be tested with
the TLS-5).
·
If a ground reference is required, connect a 0.080-inch diameter pin tip
probe to the chassis ground reference jack on the unit back panel (Figure
1).
Figure 5 shows the pin connections for the alligator clip cables used to connect
TLS-5 lines to a terminal block . See Figure 4 in
Chapter 5 for a generalized diagram of key system test connections.
Caution
When ringing is applied, the Ring lead of the modular jacks carries
up to 95 VAC referenced to ground (alternating polarity).
Be sure the TLS-5
power switch is off before handling any cord ends.
