Distance Limitations

The maximum allowable distances of a 7205H voice terminal from the System 85 and DEFINITY G2 cabinet are shown in the following table.

			NOMINAL MAXIMUM RANGE
SYSTEM	PORT BOARD	ADJUNCTS	IN FEET (METERS)
			24 AWG	26 AWG
SYSTEM 85	SN224	0	3,000 (915)	2,300	(700)
DEFINITY G2		1	1,750 (533)	1,100	(335)
		2	1,000 (305)	750	(288)

Power Requirements

The 7205H voice terminal is powered by the tip and ring leads. If the 7205H is equipped with the S101A speakerphone or the 500A headset adapter, auxiliary power will be required for the adjunct. Refer to the ADJUNCT POWER section of this manual.

The C201A call coverage module attaches to the top of the voice terminal, and the F201A func- tion key module attaches to the right side. These optional modules use the same phantom power from the switch (through the digital pairs) that also powers the 7205H voice terminal. This impacts the distance allowed from the switch.
