Increased Digital Trunking/Sdi Capacity - Nortel Meridian 1 Option 11C Planning And Installation Manual

Increased Digital Trunking/SDI Capacity

This development provides increased networking capacity for the Option 11C
and Option 11C Mini systems. Digital trunks can now be supported in any IP
Expansion Cabinet or Mini main chassis, when connected via 100BaseT or
100BaseF. A total of 45 digital trunks could be supported on Option 11C, and
15 digital trunks supported on Mini.
The following CE cards can now be supported in IP expansion cabinets/mini
main chassis.
• 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 Cabinets.
ESDI AML and TTY are not supported.)
This development also provides increased SDI/D-channel capacity. Three
SDI ports are provided with each IP Expansion Cabinet and D-Channel
capacity has been increased, such that a total of 16 D-channels are now
supported per cabinet.
Option 11C IP Expansion introduces two types of IP daughterboards:
• 100BaseT IP daughterboard
• 100BaseF IP daughterboard.
These boards are available in single and dual port versions. The dual port IP
daughterboard connects to the SSC of a Main cabinet and supports
connections to two expansion cabinets, each equipped with an SSC, via IP.
The single port IP daughterboard is used at the IP Expansion to provide
connectivity back to the Main.
The Option 11C SSC card can accommodate up to two single or dual port IP
daughterboards. The IP daughterboards can coexist with either the single port
or dual port fibre daughterboards.
