The purpose of this addendum is to document the changes introduced between Release 3 and Release 4 software. This addendum should be read in conjunction with the CLAM Bridge Reference Manual Issue 3.0 to provide a full description of the configuration and operation of the CLAM Bridge.

___________________________________________________________________________________ (co po) Enter command : If a CLAM WAN is installed in the unit, it will be automatically detected and the port will be displayed in addition to any other ports on the unit. If a WAN port is available it should be configured with reference to one of the following two sections 2.1.1 HDLC P...

This parameter should be set to the actual line speed at which (BITS/S) the interface is being clocked . Although the CLAM Bridge does not generate clocks this parameter is used to configure internal timers which optimise use of the link.

DISABLED turns data compression off. ENABLED allows the system to use its standard bandwidth optimisation algorithm for compression. This should be used on all links up to 256Kbps. FAST should be used on links with speeds greater than 256 Kbps to maintain maximum throughput on the line. The advantage of using compression depends on the data type and line speed increases.
EXP+BKUP means that when Demand Threshold values are met (see below), packets defined as EXPEDITEd in the Type Filter Table will be sent by the first additional link dialled up. It also allows the use of the BACKUP facility to dial the Remote Unit Name destination (see below) if the usual link fails.
Page 8
DEMAND Specifies the percentage loading on the link which must be THRESHOLD reached over the period of time in Demand Period (see below) before dialled-up bandwidth is requested. Each time this threshold is reached, additional bandwidth will be requested. This means that a link can request multiple connections to the same destination to add bandwidth.
Page 9
DEMAND Dial-up connections can be used to provide bandwidth on PRIORITY demand and backup of leased lines. This parameter determines the priority of this port when using a dial-up circuit for additional bandwidth. Should this port require the use of a backup dial-up circuit that is already in use, the Demand Priority will be compared with the priority used by the port which is already using the dial-up circuit.

ROTOCOL RIORITISATION Local Area Networks can support many different types of protocols, each with different transmission characteristics and requirements. It is possible for one protocol to adversely affect other protocols on the LAN by taking too much bandwidth. This problem is made worse by inserting a remote bridge link, due to the lower speed of the link compared to the LANs at either end.

the Demand Threshold, the first ISDN channel still carries EXPEDITED data, and a second ISDN channel is set up for normal data. If Backup is enabled and the leased circuit fails, the first ISDN channel is set up and initially carries both EXPEDITED and normal data. EXPEDITED data still has priority.

To configure an HDLC or ISDN port for Bandwidth on Demand, use the command CONF PORT to EDIT the Demand and Threshold parameters. Use this command if Backup is needed on an HDLC port. The field Backup/Demand Mode on the form EDIT HDLC PORT has extra options, which specify if EXPEDITED or NON-expedited (normal) data will cause Bandwidth on Demand to be allocated: EXP.DATA...
