CIM ports 4 These ports may be used to connect ASU cabinets only.
ASU supported 4
LS trunks (in ASU) 16 (32) Up to four Universal ASUs may be added with 4 LS trunks each.
Four ASU II cabinets can support 8 ONS/LS cards for a total of 32
LS trunks. Additional LS trunk cards may be added in peripheral
cabinets.
IP networking yes The system can support the maximum number of programmed IP
trunk connections to other nodes (200 IP trunks to one node, 400
SIP trunks to one node, and 2000 total trunks to all nodes).

Digital links 16 Digital trunks may be on embedded Quad BRI modules (12),
Dual T1/E1 modules (6), T1/E1 combo modules (3), or external
NSU cabinets (16).
Peripheral
cabinets
6 (+6 expanded) The number of peripheral cabinets may be doubled by using an
expanded peripheral cabinet, but this will only increase the line size
and does not increase the traffic capacity.
NSU/DSU cabinets 8 To install the maximum number of NSUs and peripheral cabinets at
the same time will require chaining of the NSUs. Note that the
maximum usable capacity may be limited by the E2T and DSP
resources before the physical capacity is reached.
