9.1. DS0
Bundles
The AN-30 supports distribution of the T1/E1 traffic across 4 sites in a cascaded PTP
topology.
To uniquely identify traffic that is destined to a specific site, requires the definition of
DS0 Bundles.
A DS0 bundle is a logical grouping of a specified number of timeslots. At least one
bundle is required for each physical T1/E1 port. DS0 Bundles can be defined starting at
any TS and running contiguously from 1 to a maximum of 24+1 timeslots (for T1 links)
and a maximum of 32 timeslots (for E1 links). An AN-30 can support a maximum of 4
DS0 Bundles.
Figure 15 illustrates a typical single hop PTP configuration back hauling 2 full rate T1/E1
lines in a mobility application. All traffic is terminating at a the same endpoints and
therefore requires definition of one DS0 bundle for each T1/E1 line.
