3300 ICP General Information Guide
28
• 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 termi-
nation (signaled or timed) and whether signaling should be fully-compelled or
semi-compelled. These features allow the individual definition of each register signaling
tone.
• PRI Links - The system supports DM-250, DMS-100, Bellcore National ISDN, 4ESS, NI-2,
5ESS NI2, NI13, Euro ISDN (CTR4) protocols, and IDA-P PRI protocol used in Hong Kong.
The system connects to PRI links through the Universal NSU or the PRI card in the DSU
cabinet or MicroLIGHT. (See Note below)
• BRI Links - The system supports Euro ISDN 2B + D, Basic Rate Interface, or the North
American ISDN-1 and ISDN-2 protocols. The system connects to BRI links using a DPNSS
link from a Universal NSU or CEPT Formatter card through the BRI NSU or the BRI card
in the DSU cabinet or MicroLIGHT.
• SIP Trunks - Allow the 3300 ICP to connect to the Service Provider through the SIP protocol
over the IP network.
The following analog trunks are supported:
• Analog CO trunks - Use the loop start (LS) ports on the ASU II or the loop start/ground start
(LS/GS) card in the peripheral unit to interface with the system.
• LS CLASS trunks - Available on the Analog Main Board and the Analog Option Board on
the MX Controller.
• E&M trunks - Use the E&M trunk card in the peripheral unit to interface with the system.
The card can be configured for either 2-wire or 4-wire operation. Type 1 through Type V
circuits are supported.
• Direct Inward Dial and Tie trunks - Use the DID/Loop Tie trunk card in the peripheral unit
to interface with the system.
Note: The NSU can be eliminated if there is a T1/E1 module installed in the 3300 ICP.
This module provides PRI and Q.SIG connectivity directly on the controller.
