Estimating Installation Time - Nortel 1000E Upgrade

DSP Daughterboards (optional)

Estimating installation time

Communication Server 1000E Upgrade
Two optional DSP Daughterboards are introduced for the MGC, the
NTDW62AA 32-port DSP daughterboard and the NTDW64AA 96-port DSP
daughterboard. These daughterboards provide DSP resources for connecting
IP and TDM devices, eliminating the need for installing Voice Gateway
Media Cards on the CS 1000E Media Gateways. However, Voice Gateway
Media Cards are still supported in CS 1000E.
When all equipment and software is available, Nortel recommends planning
a two to four hour period in which to perform the upgrade. Service
interruptions can occur during this period.
System expansions and additional installations require additional time. See
Communication Server 1000E: Installation and Commissioning (NN43041-
310) for details.
Making IP Peer Networking modifications also requires additional time
beyond that of an upgrade. It can be performed after completing a standalone
configuration upgrade. It does not require the interruption of call processing.
See IP Peer Networking: Installation and Commissioning (NN43001-313)
for details.
Upgrade and installation times depend on the following criteria:
• number and availability of technicians
• familiarity with CS 1000E
• physical location of hardware components
• interoperability products (Nortel Messaging Server 500, Symposium,
OTM)
• unit testing and system testing
• unforeseen issues
