Digital Trunk Connectivity

Universal NSU (MXe II Controller)
• Connects to MXe II Controller via a FIM link
• A second NSU can be daisy chained from the first
NSU via CIM (allows two NSUs per FIM link)
• Each NSU supports two digital links
• Both links in an NSU must run the same protocol
(T1-D4 or MSDN / DPNSS or PRI / QSIG)

Supports:
• CAS (T1-D4) – digital E&M, digital CO,
digital DID, IDA-P
• T CCS – Primary Rate ISDN, XNET over PRI,
QSIG, MSDN / DPNSS
• 1 – QSIG, Euro ISDN, XNET over PRI, DASSII,
MSDN / DPNSS
R2 NSU (MXe II Controller and AX Controller)
• Each R2 NSU supports two links
• Connects to controller via a FIM link
• A second NSU can be daisy chained from the first
NSU via CIM (allows two NSUs per FIM link)
Dual Embedded Digital Trunk Module
(MXe II Controller / AX Controller)
• Each module has two E1/T1 trunk interfaces (links)
• Provides PRI / QSIG / T1-D4 / DASS II / DPNSS / IDA-P
protocol through the controller (No NSU required)
• Each interface can run a different protocol, either PRI,
QSIG, or T1-D4
