INSTALLATION-STATION APPARATUS

SECTION 100-816-206

MARCH 1993

To accommodate the digital telephone line cord, the cable should be terminated in a modular sta- tion connector block (RJ-11) at the station location. The standard single-pair, modular digital telephone cord that is sent with the telephone is 7 feet (the maximum allowed is 25 feet).

NOTES:

1.Digital telephone cable runs must not have the following:

•Cable splits (single or double)

•Cable bridges (of any length)

•High resistance or faulty cable splices

2. See Section 100-816-208for secondary protector information.

2.20Connecting Electronic Telephones to the System (DK16 only)

2.21The following provides information on how to connect electronic telephones to the DK16 sys- tem.

NOTE:

Before proceeding, see warning and caution notes in Paragraph 2.01.

2.22Electronic telephones are connected to elec- tronic telephone circuits in the DK16 Expansion Unit on the Electronic Telephone Interface Unit (PEKU) and the Standard/Electronic Telephone Interface Unit (PESU) via the main distribution frame (MDF) with standard twisted-pair jacketed telephone cable. Two-pair wiring, as a minimum, is required for telephone connection. However, three- pair wiring is recommended to permit future up- grades, such as Off-hook Call Announce.

To accommodate the electronic telephone line cord, the cable should be terminated in a modular station connector block (RJ-11) at the station loca- tion. The standard two-pair modular electronic telephone cord length is seven feet (the maximum allowed length is 25 feet). See Wiring diagrams, Section 100-816-208for more details.

NOTE:

See Section 100-816-208for secondary pro- tector information.

The overall length of the station cable run from the DK16 key service unit (KSU) to the telephone must not exceed 1,000 feet (305 meters), if using 24 AWG cable.

2.30Connecting Standard Telephones to the System

2.31The following provides information on how to connect standard telephones to the DK8 or DK16 system.

NOTE:

Before proceeding, see warning and caution notes in Paragraph 2.01.

2.32Standard telephones connect to standard telephone circuits in the DK8 Standard Telephone Interface Unit (QSTU), telephone circuits on the DK16 Base Unit Standard Telephone Interface Unit (KSTU), the DK16 Standard Telephone Inter- face Unit (PSTU), and the DK16 Standard/Elec- tronic Telephone Interface Unit (PESU) via the main distribution frame (MDF) with standard twisted-pair jacketed telephone cable. Single-pair wiring is required. (Refer to Wiring Diagrams, Section 100-816-208, for more details.)

NOTE:

See Section 100-816-208for secondary pro- tector information.

The standard telephone cable's overall loop resis- tance, connected on- or off-premises, is 300 ohms maximum, including the telephone resistance. This also applies to all devices connected to standard telephone circuits. A standard telephone connected off-premises via the telephone network should interface with OL13A lines (or equivalent) and connect to an RJ21X FIC jack (or equivalent).

2.40Telephone Wall Mounting

2.41This section provides instructions on how to mount digital telephones and electronic telephones (DK16 only) to a wall or other vertical surface. Instructions on mounting standard telephones are not provided here; refer to the manufacturer's documentation for those instructions.
