30Description 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.
