Note:For details on expanding a peripheral node, see the Peripheral Node Expansion section of the Technical Documentation CD-ROM. SUPERSET HUB The SUPERSET HUB builds on the distributed system concept by delivering advanced digital telephony functionality for workgroups. It allows SUPERSET telephones to be cost-effectively provided where a distributed system would be too expensive. The SUPERSET HUB provides DNIC connectivity through an RJ-45 patch panel and Fibre Interface Module (FIM) connection to the host peripheral cabinet. At the peripheral cabinet, a carrier module provides the connection for the FIM and interfaces back into the system. The SUPERSET HUB may be rack-mounted or wall-mounted. SUPERSET HUB System Fail Transfer The SFT maintains telephone service in the event of system failure (such as a power outage). When the system goes into SFT mode, the SFT unit connects up to six internal POTS telephone extensions directly to the CO, bypassing the system completely. The SFT is an optional, stand-alone, wall-mounted device that connects to the system’s peripheral cabinet or main distribution frame (MDF). Each SFT can control six circuits, and up to four SFTs can be daisy-chained together for each zone, providing security for 24 internal extensions. The SFT switches to SFT mode under the following conditions: Failure of the system power converter Failure of the system main control (in a redundant system, both main control planes must fail, causing a critical alarm to all zones)
SX-2000 General Information Guide 22 Revision A 50003097 Interruption of the system AC power Failure of the peripheral switch controller (zone) Loss of the fiber link between the main control and peripheral cabinets. Power Supply All power for the SFT unit is provided from the -48 Vbat source on the system. A source of -12 V powers the electronic circuitry on the card. This supply is derived from the -48 V input and powers all the SFT circuitry except the transfer relays. The relays are powered by a transistor-regulated -41V source, also derived from the -48 Vbat input; therefore, in the event of Vbat varying between the standard -42.5 V to -56.5 V, the current drain remains constant. Transfer Relays Each circuit in the SFT uses a four form C relay to transfer between normal and SFT modes of operation. Loop Detector When a transfer relay enters SFT mode, the loop detector connects in series with the loop between the extension and CO trunk facility. This circuit prevents the extension from returning to normal operating mode before an SFT mode call is completed. When the SFT mode call is completed, the extension is returned to normal operating mode. SFT Control Leads The transfer control sensor on the SFT senses a loop closure across the SFT and SFT return (SFTR) leads. When a loop closure is sensed, the power to the relays is removed, the relays are released, and all circuits enter the transferred state. Power Consumption The total current drain for the SFT is typically 80 mA. Power Dissipation (watts) Power SupplyTYP. (Watts)TYP+20% -48Vbat3.183.81 @Vbat=-56 V3.714.45

The DNI line card provides 16 voice and data lines, and has 16 circuits. ONS Line Card The On-premises (ONS) line card connects a maximum of 16 standard telephones with line loop resistance of 400 ohms or less. As such, the ONS line card is used to connect internal telephone extensions close to the system. The ONS line card also supports modems and fax machines. The ONS line card has 16 circuits. OPS Line Card The Off-premises (OPS) line card is a digital card that interfaces a maximum of eight outside telephone extensions with the system. The card is meant to interface telephone extensions whose line loop resistance exceeds 400 ohms. As such, the OPS line card is used to connect external telephone systems whose loop resistance is anywhere from 400 to 1600 ohms (external resistance from 600 to 1800 ohms). The OPS line card has eight circuits.
SX-2000 General Information Guide 24 Revision A 50003097 Trunk Cards Trunk cards include LS/GS trunk card E&M trunk card DID Loop Tie trunk card. LS/GS Trunk Card The Loop Start/Ground Start (LS/GS) trunk card interfaces to the analog LS/GS Central Office (CO) trunks, and is used to terminate eight CO trunks (non-dial-in trunks). The LS/GS trunk card connects to any Peripheral Interface card slot on the peripheral shelf via connectors J1 and J2. The LS/GS trunk card has eight circuits. E&M Trunk Card The Ear and Mouth (E&M) trunk card provides a means of interfacing four external trunk circuits to the system. E&M trunk cards connect to any Peripheral Interface card slot on the peripheral shelf via connectors J1 and J2. The E&M trunk card ties two switches together (tie line), and supports music-on-hold. The E&M trunk card has four circuits. DID Loop Tie Trunk Card The Direct Inward Dialing (DID) Loop Tie trunk card terminates a maximum of four trunks. These trunks can be Direct Inward Dialing (DID) trunks, Loop Tie (LT) trunks, or any combination of DID and LT Trunks. Direct Inward Dialing provides direct access to system subscriber lines from the public telephone network. Loop Tie provides a means of connecting two systems together over a common trunk. The DID Loop Tie trunk card involves renting a group of numbers from the CO. With this card, outside calls are switched directly to the extension called; therefore, no attendant is required.
