SX-200 ICP CX/CXi Technician’s Handbook
Considerations:
a. Is one IP Trunk route the primary route used, and if the far end
node is down, will it use the other IP Trunking Route (assumes
a three node network)? If so, then Max calls could be set to 24
on both routes since you will only use one route at any given
time.
b. If both routes will be used and traffic is assumed to be higher
(e.g., eight calls per route at any given time), then the Max
calls would more likely be set to 12 or lower.
IP Check List
Refer to “Maintaining Voice Quality of Service” in SX-200 ICP
Documentation for more information on the subject matter discussed in
this section.
ˆ
Communicate with the engineer responsible for remote node(s) and
gather information about the IP Trunk requirements.
ˆ
Gather information about the “pipe” between your location and the far
location.
- Is it ADSL? ADSL has fast download speeds but slow upload
speeds, plus it usually relies on DHCP to provide local addressing,
which affects the programming in CDE (SX-200 ICP must have a
fixed IP Address that won't change at the far end IP Trunk
connections).
- What is the bandwidth? How much of the bandwidth will be used
for data? Are there any times of the day when the bandwidth is
utilized more than other times? Is the pipe ever removed for
general maintenance or is it susceptible to weather or
environmental impacts (anything that will affect your ability to
provide proper service). Do I need Compression Options based on
my findings (refer to the CDE Checklist at beginning of the
section)?
ˆ
Gather the IP Addresses for the far end. Ping from both ends to ensure
there is a connection.
ˆ
Using ARS, get the far end to call you and you call them.
- Refer to SMDR to get information on what you are dialing and what
is being dialed from the other end.
