3300 ICP Network Support

Voice Networking

Lines

The 3300 ICP supports the following internal voice connections:

• Ethernet connections are provided on the 3300 ICPs to connect the system to the custom-

er's Ethernet LAN. IP phones communicate with the 3300 ICP over the Ethernet LAN.

• On-Premises (ONS) lines are for industry-standard DTMF telephones. These lines are

supported by the ONSp line card in the ASU II and the AX Controller. ONSp card variants

have "protected" ports that protect the circuitry against lightning and surges. ONS ports are

also available on the Analog Main Board (AMB), or Analog Option Board (AOB).

• Digital Network Interface (DNI) lines provide an interface for Mitel legacy digital telephones

and consoles. These lines are supported by the DNI Line card connected into the SX-200

Bay.

• On the client side, SIP phones are starting to proliferate across the full spectrum of telephony

vendors.

Trunks

The system can connect to the Public Switched Telephone Network (PSTN) or to private

networks over digital and analog trunks. The following digital links are supported:

• DS1 Links - The system supports the following protocols: D4, Q.Sig, MSDN/DPNSS, Pri-

mary Rate ISDN (DM-250, DMS-100, Bellcore National ISDN, 4ESS, NI-2, 5ESS NI2), and

XNET over PRI protocols. The system connects to DS1 links through the T1/E1 Modules

or Universal NSU.

• E1 Links - The system supports DASS II, MSDN/DPNSS, Q.Sig, Primary Rate ISDN (Euro

ISDN (CTR4)), and XNET over PRI protocols. The system connects to E1 links through the

T1/E1 Modules or Universal NSU.

• R2 Links - The system supports the CCITT Blue Book, Volume VI, Fascicle VI.4, Specifi-

cations of the Signaling System R2, and Recommendations Q.440 to Q.490 (with the

exception of Echo Suppression (Q.479), Test Calls (Q.490) and international signals). The

system connects to R2 links through the R2 NSU. Note that many countries use R2 signaling

but do not adhere to the CCITT recommendations in their entirety. The 3300 ICP is com-

pletely flexible and supports regional variations of the R2 protocol. Line signaling, tone

interpretation, and timing parameters for the converter can be adapted to suit any national

or regional requirement. For example:

- Line signaling features allow you to program up to four bits to define the incoming and

outgoing patterns for line signals such as Idle and Answer

- Register signaling features allow you to program the type of address signaling

Note: Pulse and rotary dial telephones are not supported.
