the Business Communications Manager.
Figure 59 Analog telephone installation overview
external line to ATA 2 must follow the transmission network requirements
described in the data communication device specifications
transmission rates (baud) over 1,200 bps require a modulation design compatible
with the telephone line bandwidth. Use a conditioned
external line to prevent data corruption during transmission
Note: Maximum loss from the ATA 2 analog terminal to the
CO must be 10 dB or less at 1 kHz. If the loss exceeds this
limit, condition the line. This loss ensures correct data
transmission for different types of data terminals.
