Table 9-12. Asynchronous Channel Extended Features
Option Default Description
1. Data Compression Enable Selects whether compression will be enabled. When compression is
enabled, the Multiserver compresses a block of data when transmitting
and decompresses the data when receiving. Adaptive Huffman
Compression algorithms are used, so fewer bytes are required for the
transfer. Thus, throughput is increased. Both local and remote ports must
be configured for data compression before the channel will support
compression. When compression is disabled, the data transfers at normal
(slower) rates.
2. Remote CTS Forced On Allows the remote CTS signal to be strapped or transparent. The
Control selection depends on the device attached to the port.
Select Forced On when the channel is forced connected and the port is
connected to a DTE device. Remote CTS will always be high.
Select Normal when a channel is forced connected and the port is connec-
ted to a DCE device. CTS will be controlled by Pin 11 of the local port.
When configuring a feeder mux, this option will not display.
