Modes of Operation |

|
The HDLC-NRM (SDLC) implementation supports two normal response modes of transmission:
Within TWA mode, both half duplex and full duplex options are supported. There is also a restricted implementation of SDLC Loop Mode operation (see Appendix B). This mode is not available on the 2-Channel ACC Multiplexer interface. This release of the HDLC-NRM (SDLC) protocol product is qualified for use at line speeds from 4800 bits per second to 19,200 bits per second on the 8-Channel EISA and HP-PB ACC Multiplexer interfaces. When the HDLC-NRM (SDLC) protocol is used on an 8-Channel EISA or HP-PB interface in a mode where there is only a single primary or secondary broadcast terminal configured on a line, the operation of the protocol is supported at speeds up to 64,000 bits per second. On the 2-Channel interface, operation of the protocol is supported at speeds up to 128,000 bits per second. |
