Introduction
The TLA4R (

ack) board provides four ports for the analog trunk connection
(DP and DTMF signaling methods) on HiPath 3500 and HiPath 3300 (19-inch housing). There
are also two ALUM power failure transfers.
The transmission and function-oriented characteristics of the TLA4R are completely identical
to those of the
that are used in HiPath 3550 and HiPath 3350. The only differences
are
●
the two ALUMs which are only available on the TLA4R.
●
the call metering receiving equipment interface, which is only on the TLA boards.
