LAPD Server is GL's WCS based server module which runs as a special task under the GL Server. The WCS LAPD Server provides Layer 3 LAPD protocol services over GL's T1 E1 boards. It permits to create multiple LAPD links of various bandwidths (time-slots, sub-channels) and provides UDP interface to the client applications for generating & receiving LAPD payload over these created LAPD streams.
LAPD is the protocol used on ISDN's (Integrated Services Digital Network) D channel. Link Access Procedures on the D channel (LAPD), specified in ITU-T Q.920 and ITU-T Q.921, is the second layer protocol on the ISDN protocol stack in the D channel. The LAPD Server provides LAPD protocol services over GL's T1/E1 boards. It permits to create multiple LAPD links of various bandwidths (time-slots, and sub-channels) and provides UDP interface to the client applications for generating and receiving LAPD payload over these created LAPD streams.
Main Features
Provides multiple data link connections on a single physical link
Ability to detect errors and recover from lost, erred or duplicated information
Releases data link connections
Maintains flow control of transfer of data
Supports Automatic TEI Assignment Procedures
Upon detection of an error it re-initializes data link connections
Supports both User and Network end
