3.10.4 NET_{FIRST | START | LAST}_POLL_RT

FIRST: Default 1, Range 1…4093

START: Default 1, Range 1…4095

LAST: Default 3, Range 1…4095

Requirement:

NET_FIRST_POLL_RT <= NET_START_POLL_RT <= NET_LAST_POLL_RT <= NET_NO_OF_RTS.

HUB: When the HUB is establishing the network, it will start

to poll NET_START_POLL_RT. If no

poll-acknowledge (

POLL_ACK) is received within NET_MAX_POLL_SECONDS, it will continue to

poll next RT, and so on. When

NET_LAST_POLL_RT has been polled, it will start all over again

with

NET_FIRST_POLL_RT, and so on. (START … LAST, FIRST … LAST, FIRST …)

When HUB is connected to NMS, it may tell HUB to exclude some RTs from the poll-range:

• RTs that are not

defined in the NMS.

• RTs that are reported UP on another HUB.

• RTs that are tagged “Out-of-Order” (NMS Ver >= 10.0.1).

When HUB has polled (NET_LAST_POLL_RT – NET_FIRST_POLL_RT + 1) number of RTs,

without being able to lock to any RT carrier, it will RESET itself.

After the HUB has got in-lock to one of the RTs, it will send a LINK_RESET packet (to Open the

link) to each RT in the range from

NET_FIRST_POLL_RT to NET_LAST_POLL_RT.

RT: Normally Not Used, but NET_FIRST_POLL_RT defines the CLUSTER Address of this RT. See

PORT_STREAM_RT [n].

Ver >= 30.8.0

NET_FIRST_POLL_RT … NET_LAST_POLL_RT are used to identify the CLUSTER of Multi-

Inbound-Link (MIL) RTs sending on Secondary Inbound carrier to Slave-HUB. These MIBs

must be set identical on Slave-HUB and all RTs that are sending to this Slave-HUB.

NET_RT_ADDRESS on these RTs must also be within this range.
