30 Description and features
If data becomes corrupt or inoperable, you can restore backed up data to
the main database and primary flash drive from one of the following:
•
external PC Card drive
• backup flash drive
• computer over a modem connection
For more information about database backup and restore methods, refer to
Communication Server 1000M and Meridian 1: Small System Maintenance
(NN43011-700).
Support for IP connectivity
Both the Cabinet and Chassis systems support IP expansion, which
provides IP interconnection between the Main and the Expansion. This
IP interconnection enables:
• increased digital trunking capacity
•
survivable expansion
• voice distribution over a Campus Data Network
Increased digital trunking/SDI capacity
IP Expansion provides increased networking capacity for Small Systems.
Any IP Expansion, when connected through CAT5 or 100BaseF cable, can
support digital trunks. A Cabinet system can support a total of 45 digital
trunk cards. A Chassis system can support a total of 15 digital trunk cards.
IP Expansions can support the following Common Equipment (CE) cards:
• 1.5MB DTI/PRI (NTAK09)
•
1.5MB TMDI (NTRB21)
• 2.0MB DTI (NTAK10)
•
2.0MB PRI (NTAK79)
• 2.0MB PRI (NTBK50)
• MISP (NTBK22)
• SDI/DCH (NTAK02) (only DCH is supported in IP expansion; ESDI AML,
and TTY are not supported)
IP expansion also provides increased SDI/D-channel capacity: three SDI
ports are provided with each IP Expansion Cabinet/Chassis, and D-channel
capacity increases to up to 16 D-channels per IP Expansion.
Refer to "Fiber-optic and IP expansion" (page 33) for a description of the
hardware required for IP expansion.
