Connecting Telephone Service & Telephone Surge Protection
to the System
Connect the TIP and RING for each incoming phone line from the telephone company to the
TH31SRG Telephone Master Hub using a 110 punchdown tool. Up to 4 incoming lines can be
attached to the TH31SRG.
ELAN recommends using Cat-5 to make punchdowns to TH31SRG Telephone Master Hub.
See Figure 3-12 for wire punchdown color coding
NOTE: The COM2 supports up to 2 incoming lines.

The ELAN COM2 is compatible with most touch-tone telephones and multi-line telephone
systems. Certain telephones that use the both # or * buttons for other functions may not be
compatible.
The ELAN COM2 has a Ringer Equivalency Number (REN) of 0.7A. The maximum number of
telephones that may be connected in a home is dependent on the Ringer Equivalency Voltage
being provided to the home by the phone company and the Ringer Equivalency Number of
each telephone in the home. When added together, the REN of all the house phones plus the
COM2 should not exceed 5 per telephone line.
Exceeding the Ringer Equivalency Voltage provided by the telephone company may result in
intermittent or no ring-in or a call from your local carrier. Ring boosters are available from your
phone company for a nominal fee. ELAN strongly recommends the use of telephone line surge
protection between the incoming phone line and the COM2 Phone Input.
ELAN recommends that telephone RJ-45
jacks be wired to the T568A standard.
