4-Wire Switched 56 DBM Technical Specifications

Specifications

Criteria

 

 

APPLICATION

Full- or half-duplex data transmission via 56 kbps switched services

 

compatible with AT&T, MCIr, and US SPRINTr using 4-wire switched

 

access to a local exchange carrier (LEC) or an inter-exchange carrier

 

(IEC)

 

 

COMMUNICATION LINE

A dedicated 4-wire access or a local exchange carrier 4-wire switched

 

access

 

 

PORT RATES

Async or Sync rates: 56, 48, 38.4, 32, 28.8, 19.2, 18.8, 18.0, 16.8, 14.4,

 

12.0, 9.6, 9.2, 8.4, 7.2, 4.8, 4.4, 4.0, 2.4, 2.0, and 1.2 kbps

 

Other asynchronous rates (e.g., 150, 300, 600, and 1800 bps) can be

 

obtained through oversampling

 

Asynchronous rates support CCITT V.14 extended rate range at

 

8 to 12 bits per character, including the start and stop bit (+2.3, ±2.5

 

percent overspeed/underspeed compensation at 10 bits per character)

 

 

DATA RATES

56 kbps (Note that the 4-wire Switched 56 DBM or 3600 Series DBM-S

 

uses proprietary rate adaption to support data rates of less than

 

56 kbps.)

 

 

DBM COMPATIBILITY

If Call Setup is set for Callback or Password security, then the

 

device is compatible with a 3600 Series Switched 56 DBM only.

 

If Call Setup is set for Alarm or None, then any Switched 56 kbps

 

terminal interface unit (TIU) can be used.
