Connectivity Figures

Figures 4-21 through 4-31provide connection information for various equipment. These

figures have been included as		an aid to	understanding	how equipment can be	connected to
S y s t e m 2 5 a n d t o i n d i c a t e r e q u i r e d			c o n n e c t i n g a n d s u p p o r t i n g e q u i p m e n t . O t h e r
a r r a n g e m e n t s	a r e p o s s i b l e ;	t h e s e f i g u r e s can be		useful in developing	connecting
arrangements	for new or customer-provided equipment.

The PEC codes have been noted on the figures, as have indications of the source for obtaining non-PEC equipment (eg, from installer or furnished with other equipment). This information can be of use to Account Executives and Technical Consultants who are adding equipment to existing installations. For new installations, the DOSS Configurator must be used to select equipment requirements. For existing installations, you will need to determine what equipment is already installed. Y OU should not order equipment directly using the PECs in these figures. The octopus cable (PEC 2720-05P), for example, supports eight terminals; you do not order one per terminal.

A list of related PECs, Apparatus, and Comcodes is provided in Section 7. Be sure to check the Sales Manual and/or DOSS before ordering since this information changes frequently.

Symbols Used in Figures: Modular jacks are shown by the triangle symbol. The 25-pair connectors are indicated by shaded blocks. Generally, only one leg of an octopus cable is shown. Unterminated wiring requiring cut down or other termination do not have symbol designations. The 103A Connecting Block is a typical modular wall jack that provides cut- down connections for building (station) wiring.

Voice Terminal and Adjunct Connections

Figures 4-21 through Figure 4-27provide connection information for single-line and multiline voice terminals. The single-line terminals can be located on-premises, off- premises, or out-of-building. The 7300H series multiline voice terminals can be used for out- of-building service but must be within 2000 feet of the system cabinets (local power is required beyond 1000 feet). Off-premises service is not available.

Diagrams for voice terminal adjunct connections are integrated with the specific feature descriptions in Section 2.

Attendant Console Connections

Diagrams for attendant console connections are included in the “Attendant Console” descriptions in Section 2.

Peripheral Equipment Connections

Diagrams for peripheral equipment connections are integrated with the specific feature descriptions in Section 2.

ADU Connections

Figures 4-28and 4-29provide connection information for data terminals and associated single-line or multiline voice terminals. The voice terminal and data terminal leads are separated at the SIP with a Y-adapter and are connected to their respective station ports. Figure 4-30presents a typical Multiple Asynchronous Data Unit (MADU) connection.

Figure 4-31shows local power connections for Z3A1, Z3A2, and Z3A4 ADUs.

Auxiliary Equipment Connections

Diagrams for auxiliary equipment connections are integrated with the specific feature descriptions in Section 2.
