Description of the Multimedia Stretch Tap - TA
The Multimedia Strech™ Tap - Technician Access (MST-TA) is available in a range
of port configurations and tap values. Interchangeable directional couplers (DCs)
facilitate changing tap values to equalize the RF plant.

The faceplate has a technician access panel, which allows access to the positive
temperature coefficient resistors (PTCs) on the circuit board. In networks where a
twisted pair wire is needed, the technician access panel can be completely removed
and the Twisted Pair module added.

Features
The tap has the following important features:
Patented Connection Beam AC/RF bypass allows for removal of the tap
faceplate without interrupting downstream customer service.

New cable provides a high current (12 A) through rating to allow for passing the
additional power required for telephony services.

Power passing is selectable on each drop, allowing AC power to flow to a
subscriber’s telephone interface unit where needed.

9-inch housing spans the typical gap left in the feeder cable after removing old
taps. This allows for tap upgrades without adding splices or extension
connectors to the feeder cable.
