Lines and Trunks

Lines

The system supports the following types of internal voice lines:

•A 10/100BaseT Ethernet connection is required for Mitel Networks IP telephones to connect through an Ethernet LAN to a 3300 Controller. These lines are supported by the 3300 controller.

•On-Premises (ONS) Lines (24V per port) are for industry-standard DTMF analog telephones. The external loop resistance on an ONS line must be 600 ohms or less, and the loop length must be 5000 ft (1500m) or less on 26-gauge wire. These lines are supported by the 3300 Universal ASU, the 3300 ASU and the ONS line card in the peripheral cabinet.

•Off-Premises (OPS) Lines (48V per port) are for industry-standard telephones where the external loop resistance exceeds 600 ohms or where lightning surge protection is required. The maximum resistance on an OPS line must be 1800 ohms or less, and the loop length must be 19,000 feet (5800m) or less on 26-gauge wire. These lines are supported by the OPS line card and are only available if a peripheral cabinet is installed.

•Digital Network Interface (DNI) Lines provide an interface for Mitel Networks digital telephones, and consoles. The maximum loop resistance on a DNI line must be 280 ohms or less, and the loop length must be 3300 feet (1000m) or less on 26-guage wire. These lines are supported by the DNI Line card and are only available if a peripheral cabinet is installed.

Trunks

The system can connect to the Public Switched Telephone Network (PSTN) or to private networks over both digital and analog trunks.

The following digital links are supported:

•DS1 Links - The system supports D4, Q.Sig, MSDN/DPNSS, Primary Rate ISDN (DM-250, DMS- 100, Bellcore National ISDN, 4ESS, NI-2, 5ESS NI2, NI13), and XNET over PRI protocols. The system connects to DS1 links through the 3300 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 3300 Universal NSU.

•R2 Links - The system supports the CCITT Blue Book, Volume IV, Fascicle VI.4, Specifications of the Signaling System R2, 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 3300 R2 NSU.

•PRI Links - The system supports DM-250, DMS-100, Bellcore National ISDN, 4ESS, NI-2, 5ESS NI2, NI13, and Euro ISDN (CTR4) protocols. The system connects to PRI links through the 3300 Universal ASU or the PRI card in the DSU cabinet.

•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 through the 3300 BRI NSU or the BRI card in the DSU cabinet.

The following analog trunks are supported:

•Analog CO trunks interface to the system by using the Loop Start (LS) ports on the 3300 Universal ASU or the Loop Start/Ground Start (LS/GS) card in the peripheral cabinet.
