Step 4: Telephony Service Cutover
Determine how traffic can be rerouted during service cutover for
certain blocks. Can hunt groups be used? Can the lines be put into
maintenance mode?
Create a list of numbers to call before service cutover to verify that
wiring is correctly installed.
Create a list of numbers to call after service cutover to verify that Span
settings are configured correctly.
The following general cutover plan is suggested to avoid adverse impact to
the telephony network if wiring or configuration problems occur.
1.
Ask the onsite telco personnel to place the first circuit out of service.
2.
With the Appliance powered on, make the telco connection for the first
Span. See "Connecting the Telco Cable(s)" on page 156 for instructions
for connecting the telco cables to the Appliance telco ports.
3.
Verify wiring, and then cut over the Span.
For Analog Spans, the Span is inline when you connect the telco
cable to the powered-on Appliance.
For digital Spans on any Appliance type, place the Span inline by
typing the following series of commands via Console connection,
Telnet, or the
ASCII Management Interface
for the Span.
SPAN INLINE
RESTART
You can select multiple Spans at once to place inline via the
ASCII
Management Interface
.
4.
Verify Span configuration and operation using the procedure in "Post-
Cutover Verification" on page 158.
5.
Repeat for each Span.
(TDM Appliances Only) To connect the Appliance telco cable(s)
Depending on your Appliance type, follow your service cutover procedures
to do the following:
ETM 1012/1024 Analog Spans
1.
Connect the cable from the demarcation point or point of presence to
the Appliance port labeled
Network
and the cable from the PBX or
station to the port labeled
CPE
.
2.
Determine the onhook voltage by issuing the
SHOW POTS
ETM
Command while the line is onhook.
