You should review this chapter if you are responsible for configuring polled AOT
on one or more Bay Networks routers. If you are already familiar with polled A OT
concepts, you can go directly to Chapter 2, “Enabling Polled AOT,” for
information about starting polled AOT on Bay Networks routers.
Polled AOT Networking
Polled AOT is a wide area network (WAN) protocol that enables transport of
asynchronous data packets over a TCP/IP network. Unlike synchronous
transmission, asynchronous transmission does not use clocking signals to time the
data transmission. Instead, asynchronous transmission uses start and stop bits to
control the transmission.
Polled AOT transmissions use TCP timers and keepalive settings to ensure that
there is an active TCP connection between two routers before any transmission
attempt. The router that you designate as the primary router transmits polls to a
secondary router over the active TCP connection. Because asynchronous
transmissions are relatively slow (300 b/s to 9600 b/s), polling ensures that the
secondary router is available for asynchronous transmission.

In one sample application (F
igure 1-1), banks can use polled AOT to connect
alarm hosts to remote alarm panels. When an alarm host is connected to a local
Bay Networks router, the local router can establish a TCP/IP connection with a
remote router connected to an alarm panel. The local router receives the
asynchronous data packet from the alarm host and sends it over the TCP/IP
connection. When the remote router receives the packet, it strips the TCP/IP
information and forwards the alarm information to the alarm panel.

Polled AOT Configurations on Bay Networks Routers
To configure a Bay Networks router for polled AOT, you use Site Manager’s
Configuration Manager on a PC or UNIX workstation. You configure polled AOT
on a port-by-port basis. Table 1-1 lists the router platforms and the modules that
support polled AOT.

To create a polled AOT configuration, you must perform the following steps:
Designate one router as the primary and the other router as the secondary.
1.
In multipoint configurations, you can designate additional secondary routers.
2.
Configure a router AOT Peer Table, where you define which router (primary
or secondary) will initiate the TCP connection.
3.
Edit the polled AOT line parameters.

You enable polled AOT on your Bay Networks router by configuring it on each
interface you want to use for polled AOT transmissions. When you enable polled
AOT, you must specify certain parameters; the Configuration Manager supplies
default values for the other parameters. If you want to edit parameters, see
Chapter 3, “Editing Polled AOT Parameters.” Appendix A describes the polled
AOT parameters.

Enabling Polled AOT
The Edit AOT Interface window (F
igure 2-2) allows you to configure individual
interfaces for polled AOT transmissions. Specifically, you must perform the
following steps:
1.
Configure the interface to a primary or secondary router.
2.
Specify the type of interface: point-to-point or multipoint.
3.
Specify the TCP connection parameters.
117350-A Rev. A
Figure 2-2. Edit AOT Interface Window
To configure a pair of routers to transmit polled AOT data, you designate one
router as the primary and the other router as the secondary. (For example, the
primary router is the one connected to the alarm host.)
Use the Interface Attached To parameter to specify whether the router you are
configuring is a primary or secondary router. The primary router transmits polls to
a secondary router over the activ e TCP connection. The secondary router receives
and responds to polls from the primary router.
2-3
Page 22
Configuring Polled AOT Transport Services
Use the Interface Type parameter to specify whether the interface has one or many
TCP connections. Point-to-point provides one TCP connection to the peer router.
Multipoint provides many TCP connections to one or more peer routers. A
multipoint connection can also be one TCP connection to multiple peer routers. A
primary interface can have either a point-to-point or multipoint connection. A
secondary interface can have only a point-to-point connection to the primary
router.
Polled AOT transmissions use TCP timers and keepalive settings to ensure that
there is an active TCP connection between two routers before any transmission
attempt. Because asynchronous transmissions are relatively slow (300 b/s to
9600 b/s), polling ensures that the secondary router is available for asynchronous
transmission.

Polled AOT Parameters
Page 34
Configuring Polled AOT Transport Services
Parameter: Interface Type
Path: Configuration Manager > Protocols > AOT > Interfaces
Default: None
Options: Point-to-Point
| Multipoint
Function: Specifies whether the interface has one or many TCP connections.
Point-to-point provides one TCP connection to the peer router. Multipoint
provides many TCP connections to one or more peer routers. A multipoint
connection can also be one TCP connection to multiple control units (CUs). A
primary interface can have either a point-to-point or multipoint connection. A
secondary interface can have only a point-to-point connection.
Instructions: If this is a primary interface, select Point-to-Point or Multipoint; if this is a
secondary interface, select Point-to-Point.
MIB Object ID: 1.3.6.1.4.1.18.3.5.21.2.1.6
Parameter: TCP Keepalive Int (sec)
Path: Configuration Manager > Protocols > AOT > Interfaces
Default: 120
Options: 0 to 86400 seconds
Function: Specifies how often the local router sends a signal to the remote peer router to
verify that the peer router is working correctly and can receive messages.
If the remote peer router does not acknowledge a keepalive packet, the local
router retransmits the keepalive packet. You should set the keepalive interval
based on the total time it takes to send and receive acknowledgment from the
remote peer router.
Since keepalive packets are sent only on idle lines, increasing the keepalive
interval may decrease the cost of an idle network. For busy networks, the
keepalive interv al is not necessary because frequent TCP transmissions perform
the same function as a keepalive interval.
Instructions: Specify an appropriate value for the network. Bay Networks recommends that
you set this parameter to the same value as the remote peer router to maintain
synchronization.

Polled AOT Parameters
Parameter: TCP Keepalive Retry Timeout (sec)
Path: Configuration Manager > Protocols > AOT > Interfaces
Default: 4
Options: 0 to 600 seconds
Function: Specifies the maximum amount of time between each successive retransmission
of keepalive packets. If the local router does not receive an acknowledgment
within the TCP keepalive retry timeout, it retransmits the keepalive packet. The
router continues to retransmit the keepalive packet at every TCP keepalive retry
timeout until it receives an acknowledgment from the remote peer router, or
until TCP reaches the keepalive retry count setting.
Instructions: Specify a value in the range 0 to 600.
MIB Object ID: 1.3.6.1.4.1.18.3.5.21.2.1.10
Parameter: TCP Keepalive Retry Count
Path: Configuration Manager > Protocols > AOT > Interfaces
Default: 5
Options: 0 to 99 seconds
Function: Specifies the number of times that TCP attempts to establish or maintain a
connection. If TCP does not receive an acknowledgment after a series of retries,
TCP makes no additional attempts to establish a connection.
Instructions: Specify a value in the range 0 to 99 seconds.

Polled AOT Parameters
Parameter: Local TCP Listen Port
Path: Configuration Manager > Protocols > AOT > Interfaces > Peer Table > Add
Default: None
Options: 1000 to 9999
Function: Specifies the local router’s TCP port number, which the remote peer router will
use to establish a TCP connection. This parameter is available only when you
set the Connection Originator parameter to Partner.
Instructions: Specify a valid, available port number for this router. Be sure to use the same
value for the Peer TCP Listen Port parameter on the remote peer router.
MIB Object ID: 1.3.6.1.4.1.18.3.5.18.3.1.7
Parameter: Peer TCP Listen Port
Path: Configuration Manager > Protocols > AOT > Interfaces > Peer Table > Add
Default: None
Options: 1000 to 9999
Function: Specifies the remote peer router’s TCP port number , which the local router uses
to establish a TCP connection. This parameter is av ailable only when you set the
Connection Originator parameter to Self.
Instructions: Specify a valid, available port number for the remote peer router. Be sure to use
the same value for the Local TCP Listen Port parameter on the local router.

Parameter: Pasync Parity Type
Path: COM Connector > Edit Line > Edit SYNC Parameters
Default: Even
Options: Odd
Function: Sets the error-detection method for isolating altered or damaged polled AOT
packets during transmission. Asynchronous equipment typically adds a parity
bit to the end of a packet before transmission. This allows the recei ving router to
detect a transmission error if it receives a packet with an unexpected parity.
Instructions: Click on Values and select a value that is appropriate for your network.
