Chapter 7 — Meridian Modular Telephones
Closet power supply
Closet power can be obtained from an AC transformer for loops of 100 ft.
(30 m) or less, or a DC transformer for loop lengths of 650 ft. (197 m) or less.
An equivalent power source can be used but must maintain isolation of
outputs to the terminal. (Refer to
When using closet power, do not plug the TELADAPT connector into
any equipment (computer, modem, LAN card) other than the Meridian
Modular Telephone, as damage to equipment may result.
All terminals must be isolated from the input winding and each terminal must
be isolated from all other terminal windings. A separate winding is required
for each terminal, and grounds should not be connected.
Note: The QUT1 closet power supply source is not compatible with
Meridian Modular Telephones.
The AC source should be rated at 29 V AC, 700 mA isolated. The DC source
should be rated at 42 V DC, 300 mA isolated, with current limiting output of
1 amp.
