7 Ensure that any other paperwork or correspondence you send with
the returned equipment reflects the Encore Networks RMA number.
Note: Unless otherwise agreed in a purchase order or contract,
RMA numbers are valid for thirty (30) days from the date of
issuance in the United States, Canada, and Mexico, and for sixty (60)
days in all other countries. If Encore Networks does not receive the
equipment to which the RMA number has been assigned within the
valid time frame, the RMA will be closed. Regardless of warranty
status, if equipment bearing this RMA number is received after the
time frame closes, it may be refused or there may be a charge for
repair.
1.3 Connecting the SP201-SA to the Telephony Network
The trunk ports (DS1s) are the physical interfaces through which the
external network user equipment communicates with the SP201-SA.
On the two-port SP201-SA (Figure 1-1), port 1 carries one signaling protocol
and port 2 carries another signaling protocol. Port 1 allows a choice of
connector interface.

On the four-port SP201-SA (Figure 1-2), ports 1 and 2 carry one signaling
protocol and ports 3 and 4 carry another signaling protocol. Ports 1 and 3
allow a choice of connector interface.
