The ASPP MIB provides the configuration and operational information on asynchronous polled protocols such as the asynchronous security protocols that alarm monitoring companies use. The protocols are handled in passthrough mode. ASPP will handle the receiving and sending of the asychronous blocks. It will not perform any error checking. It is the responsibilty of the end-station to perform any required error recovery. A generic protocol has been created to support asychronous protocols. In some situations this doesn't work for all types since there is no alarm protocol standard. Specific vendor support has been included for the following vendor's alarm equipment and protocols: * adplex * adt - PollSelect - VariPoll * diebold * mdi * mosec (mosler) * gddb (Guang Dong Development Bank) - This protocol is similar to Burroughs Poll/Select The following example configuration shows how the ASPP MIB returns ASPP information, from either CISCO A or CISCO B. Security == ASP == Cisco == IP == Cisco == ASP == Alarm control A Network B Panel station The following entities are managed: 1) ASPP ports (serial interfaces) The ASPP ports are identified by the interface index, and additional information about this interface can be obtained from the Cisco Serial Interface MIB.

Added Asynchronous Point of Sale(POS) to IP conversion
support.
The APOS protocol utilizes asynchrounous communications
with 1 start, 1 stop and 7 data bits with even
parity. The connection to the POS terminal will always
be an asynchronous leased line. The protocol has many
characteristics of BSC except it is simplified to
minimize overhead on the point to point connection.
The added APOS traffic will be locally acknowledged
unlike the other polled asynchronous protocol which
function in passthrough mode.
The LRC/VRC will be verified and any necessary recovery
will be done by the router.
This is necessary since we are converting the protocol
so the data can be passed to an IP attached host.
