The TDA multiplexes analog audio signals and low-rate data signals
into E1 signals, and maps the E1 signals into VC-4s. It also
performs the reverse process.
The TDA is a multiple-channel audio and data access board.
The TDA provides two-/four-wire audio interfaces and serial data
interfaces to access 64 kbit/s audio signals and up to 19.2 kbit/s
serial data signals.
Provides four RS-232 interfaces, four RS-422 interfaces, and 12
audio interfaces. The cable inputs audio and data signals from the
front panel by using a 2 mm HM connector and outputs audio and data
signals to the front panel also by using the 2 mm HM connector.
Provides 12 two-wire audio interfaces or six four-wire audio
interfaces or a combination of two-wire audio interfaces and
four-wire audio interfaces.
The audio interface can be set to an audio interface with power
feeding or without power feeding by using the T2000.
NOTE:
The two-wire analog audio interface with -48 V DC power feeding
requires the AC impedance of the user equipment to be approximately
600 ohms. You can use this interface to connect an ordinary
telephone. The two-wire analog audio interface without power
feeding also requires the AC impedance of the user equipment to be
approximately 600 ohms. You can use this interface to connect a
private line modem.
The audio interface requires an impedance of approximately 600 ohms
and supports a transmission distance of 4000 meters. The RS-232
interface supports a transmission distance of not more than 15
meters and the RS-422 interface supports a transmission distance of
1000 meters.
Supports inloop and outloop so that services can be tested and
faults can be located quickly.
Supports the SNCP and MSP for services at the VC-12 level.
