MUSICAM USA offers three different TA modules, the TA101, TA201
and TA301. The TA101 and TA201 both provide an ‘S/T’ interface and
require an external network interface device (NT-1) for use in North
America. Elsewhere, the NT-1 is provided by the phone company, and
an external NT-1 is not required. The TA301 provides a ‘U’ interface
through its built-in NT-1 and therefore can be used only in North
America.
Connect the ISDN line to your internal terminal adapter (if so
equipped). Be sure that there are no alarm conditions present on the
terminal adapters or the NT-1. There should be no flashing LEDs or
other alarm indications for proper operation. The TA201 and TA301
terminal adapters have sanity LEDs that can be observed from the back
of the
RoadRunner
. The green LED must be solid ON for proper
operation. If using an external NT-1 with your terminal adapter, the
‘U’ interface (the wall connector) requires a 2-conductor cable. The
‘S/T’ interface (the
RoadRunner
side) requires an 6-conductor cable.
Two non-TA digital interfaces are also available for the
RoadRunner
.
The DIF101 interface is used for connecting transmission systems using
X.21, RS422, RS449 or RS530 interfaces. The DIF102 interface connects
to transmission systems using the V.35 protocol.
All audio inputs and outputs are through industry standard connectors
located on the front and rear panels. Two balanced XLR microphone
inputs are located on the front panel as are two standard ¼” headphone
jacks. An additional balanced input, switchable between microphone
and line levels, is located on the rear panel. Also on the rear panel is an
XLR balanced line level output for received audio from the far end unit
and two ¼” unbalanced local and return audio outputs to feed
recorders, PA systems, etc.
The four relay outputs and optically isolated inputs are accessed
through the DB-25 connector, and there is a DB-9 connector for
ancillary data, remote control and software upgrades. Connectors for
AC power (100-240 VAC, 50/60 Hz) and 12 VDC power are also located
on the rear panel, as is the power switch.
