The system provides an acceptable level of echo performance if the ERL and SFRL are met. Peak Noise Level nAnalog to analog — 20 dBrnC (decibels above reference noise with C-filter) nAnalog to digital — 19 dBrnC nDigital to analog — 13 dBrnC Echo Path Delay nAnalog port to analog port — < 3 ms nDigital interface port to digital interface port — < 2 ms Service Codes Service codes (for the United States only) are issued by the Federal Communications Commission (FCC) to equipment manufacturers and registrants. These codes denote the type of registered terminal equipment and the protective characteristics of the premises wiring of the terminal equipment ports. Private line service codes are as follows: n7.0Y — Totally protected private communications (microwave) systems n7.0Z — Partially protected private communications (microwave) systems n8.0X — Port for ancillary equipment n9.0F — Fully protected terminal equipment n9.0P — Partially protected terminal equipment n9.0N — Unprotected terminal equipment Station-to-station ERL should meet or exceed 18 dB SFRL should meet or exceed 12 dB Station to 4-wire trunk connection ERL should meet or exceed 24 dB SFRL should meet or exceed 14 dB Station to 2-wire trunk connection ERL should meet or exceed 18 dB SFRL should meet or exceed 12 dB 4-wire to 4-wire trunk connection ERL should meet or exceed 27 dB SFRL should meet or exceed 20 dB

Facility Interface Codes A Facility Interface Code (FIC) is a five-character code (United States only) that provides the technical information needed to order a specific port circuit pack for analog private lines, digital lines, MTS lines, and WATS lines. Table 1-16 through Table 1-18 list the FICs. Included are service order codes, Ringer Equivalency Numbers (RENs), and types of network jacks that connect a line to a rear panel connector on a carrier. Table 1-16.

Hardware Configurations Page 2-1 Multi-Carrier Cabinet 2 DEFINITY Enterprise Communications Server Release 6 Maintenance for R6r Volumes 1 & 2 555-230-126 Issue 2 January 1998 2 2Hardware Configurations The DEFINITY System supports a variety of configurations consisting of a PPN and up to 21 EPNs. In addition, the system may use a Center Stage Switch (CSS) consisting of one or two Switch Nodes. This chapter describes the PPN and EPN cabinets, and the configuration of carriers and circuit packs within these cabinets. Multi-Carrier Cabinet The Multi-Carrier Cabinet (J58890A) accommodates from one to five circuit pack carriers, and is always used for the PPN. EPNs may use either multicarrier cabinets or single-carrier cabinets. The power unit in the bottom of the MCC cabinet supplies AC voltage or DC voltage from an external source to the power supply in each carrier. The AC powered cabinet optionally contains a battery charger and backup batteries to provide temporary power to the cabinet if the external source fails. The backup unit is optional for systems powered from an Uninterruptible Power Supply (UPS). The fan unit in the middle of the cabinet cools the carriers. AC-powered cabinets have two 120V AC receptacles in the back for use as an AC power source. These can be used to power the G3-MT. Each cabinet must be connected to one of the following dedicated power sources: n120V AC 60 Hz at 50A from a National Electrical Manufacturing Association (NEMA) 5-50R power outlet or equivalent nSingle phase 240V AC, or three phase 208V AC, 60 Hz at 30A from a NEMA L 14-30R power outlet or equivalent

Multicarrier Cabinet (J58890A) Configurations Processor Port Network Cabinet The PPN cabinet, pictured above, is the primary cabinet in all G3r systems. It contains the Switch Processing Element (SPE) that controls the system and one Port Network that is interconnected by the daisy-chained TDM/LAN bus. If the system has a CSS, the PPN cabinet also contains a switch node. The individual carriers are described in following sections. The A position always contains a PPN Control Carrier (J58890AP), also known as the Processor Carrier, which holds the SPE circuit packs. If the system has a duplicated SPE, the B position holds a second PPN Control Carrier. At least one, and up to four, Port Carriers (J58890BB) can be located in the other four carrier positions, depending on traffic needs and whether the system uses those positions for other types of carriers. In general, Port Carriers are added in the sequence, B-C-D-E, unless those positions are used otherwise, as follows.

DEFINITY Enterprise Communications Server Release 6 Maintenance for R6r Volumes 1 & 2 555-230-126 Issue 2 January 1998 Hardware Configurations Page 2-3 Carriers in Multi-Carrier Cabinets 2 If the system has a Center Stage Switch, the E position holds a Switch Node Carrier. In a CSS system with duplicated PNC, the D position holds a Switch Node Carrier that duplicates the one in E position. In large systems requiring a CSS with two Switch Nodes, the second SN is located in an EPN cabinet, for both simplex and duplicated systems. Systems that have added a CSS configuration after the original installation may have their first SN in an EPN cabinet. Expansion Port Network Cabinets When used for an EPN, the multicarrier cabinet supports one Port Network with a daisy-chained TDM/LAN bus, or, optionally, two separate PNs if the cabinet does not contain a Switch Node. A cabinet with two PNs has two separate TDM/LAN bus daisy-chains. One TDM/LAN bus between carriers in positions A, B and C supports the first PN, and another TDM/LAN bus between positions D and E supports the second PN. Figure 2-1 shows locations of carriers in EPN cabinets. Each EPN cabinet contains one Expansion Control Carrier (J58890AF) located in the A position. In cabinets with one PN, up to four Port Carriers are added as needed in the sequence B-C-D-E, unless the D or E positions are used for a Switch Node. Cabinets with two PNs use optional Port Carriers in the B position, and then the C position for the first PN (above the fans). The second PN, (below the fans), is configured with the first Port Carrier in the E position and an optional second Port Carrier in D position. In large systems with a CSS that requires two Switch Nodes, the second SN is located in an EPN cabinet (this is usually cabinet number 2, PN number 2). This EPN may not be remoted by a DS1CONV complex. An EPN with an SN has a Switch Node Carrier in E position. In systems with duplicated PNC, (Critical Reliability option), the D position holds another Switch Node Carrier that duplicates the one in E position. Carriers in Multi-Carrier Cabinets PPN Control Carrier (J58890AP) The PPN Control Carrier contains dedicated slots used for circuit packs that compose the switch processing element (SPE). It does not contain port circuit pack slots. This carrier always resides in position A of the PPN cabinet. In a system with a duplicated SPE, a second PPN Control Carrier resides in the B position of the PPN cabinet.
