RE: [RPRWG] Phy Layer question




Hi Wolfi,

That is right.  There are only 4 bits in the K1/K2 for src / dst address.
Only 14 of the 16 addresses are usable.
But RPR has its own addressing mechanism.  The debate is whether we should /
should not ignore the LOS, LOF,
AIS-L, etc alarms (through SF) from sonet and replace them with new RPR
alarms.

Hi Angela, hi Vasan,

one more comment on using APS functionality of SDH:

according ITU-T Rec. G.841 max. 16 nodes per ring are supported.
In 802.17-rings we will have more nodes (max.).

(I guess thats also one of the reasons why Cisco does not use K1/K2)
