Use the following command to assign each port on the module to one of the backplane segments on the ShuntBus or isolated segments on the module:

SET PORT {slot.port} NETWORK {network}

5. Assign RI/RO ports to network segments.

If you have configured ports 17 and 18 as RI/RO trunks, you can assign them to a network using the following command:

SET TRUNK {slot} RING_IN NETWORK {network} or

SET TRUNK {slot} RING_OUT NETWORK {network}

In this command you do not need to specify port number for the trunk as port 17 is always RING_OUT and port 18 is RING_IN.

Note: If you assign a RING_IN (or RING_OUT) trunk to a segment, the other trunk will automatically be assigned to the same segment.

6.Set compatibility mode for the trunk ports.

Ports 17 and 18, when configured as trunks, can be used to connect your 8260 to another hub. Depending on the hub to which the trunk is attached you must set the following compatibility mode for the trunk:

∙

∙

8260

This is used when the trunk is connected to another 8260.

ONcore

∙

∙

This is used when the trunk is connected to a Chipcom ONcore switching hub.

8250

This is used when the trunk is connected to an 8250 or 8228.

ONline

This is used when the trunk is connected to a Chipcom ONline switching hub.

∙8230

This is used when the trunk is connected to an 8230.

All of the current 8260 trunk compatibility modes can be summarized as two different modes:

a.8250/8230/ONline

In this mode, the trunks open when enabled as long as a signal can be passed through the trunk connection. A jitter attenuator is also required for the trunks to unwrap. There is no phantom involved, and there is no special protocol involved. Wrapping of the port in the case of a fault is triggered only by the presence of beacon frames. If the module detects a beaconing ring and decides the problem is being caused by someone

or something attached to it, it will first wrap the trunks and see if the ring recovers. If it does, the module goes to a ″schedule″ for retesting the

trunks to see when it recovers. If the module does not recover, it goes on to removing other ports on that ring until the ring recovers.

b.8260/ONcore

In this mode, phantom is generated on the RI trunk and/or required to be detected on the RO port for the RI trunk and/or required to be detected on the RO port for the trunks to insert. Also a jitter attenuator is not
