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.
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 technical specifications of the TDA include the parameters specified for electrical interfaces, dimensions, weight, and power consumption.
Table 1 lists the parameters specified for the electrical interfaces of the TDA.
| Parameter | Value |
|---|---|
| Nominal bit rate | Audio: 64 kbit/s Digital signal: 19.2 kbit/s |
| Interface impedance | Audio: 600 ohms |
| Maximum transmission distance (m) |
|
| Connector | 2 mm HM connector |
The mechanical specifications of the TDA are as follows:
The maximum power consumption of the TDA at room temperature (25°C) is 12.0 W.
