Pin Descriptions

PIN NAME

DESCRIPTION

1

Ring

Ring provides one half of the two-wire connection to the telephone line. Ring

is isolated from all other circuitry. The XE1060 provides a 1500 Volt

isolation barrier; the remaining XE10X0 models provide a 3750 volt isolation

barrier. This isolation must be preserved throughout the system. This

isolation can be maintained by selecting properly rated components and

maintaining sufficient creepage and clearance distances.

2

Tip

Tip provides one half of the two-wire connection to the telephone line. Tip is

isolated from all other circuitry. The XE1060 provides a 1500 Volt isolation

barrier; the remaining XE10X0 models provide a 3750 volt isolation barrier.

This isolation must be preserved throughout the system. This isolation can

be maintained by selecting properly rated components and maintaining

sufficient creepage and clearance distances.

3

/OH

/OH is an active low input to the XE10X0 DAA module. It controls the internal

hookswitch. A low on OH closes the hookswitch and connects the

equipment to the telephone line.

4

/MUTE

This active low input provides low impedance pulse dialing in the XE1040,

XE1050, and XE1070. Presenting a low impedance to the telephone line

during pulse dialing is required in many European countries including

Germany, France and Italy.

5

T1

T1 provides half of the differential input/output connection to the secondary

side of the internal telephone line transformer.

6

T2

T2 provides half of the differential input/output connection to the secondary

side of the internal telephone line transformer.

7

GND

This pin provides ground reference for the RI, /OH and /Mute control lines.

There is no connection between ground and the telephone line (primary) side

of the XE10X0 DAA.

8

RI

Ring Indicate is an active high output from the DAA module. When a valid

ring signal appears on Tip and Ring, the DAA provides a pulse train at ring

frequency on RI.

9

VCC

This pin provides 5 volt DC power for the RI, /OH and /Mute control lines.

There is no connection between VCC and the telephone line (primary) side of

the XE10X0 DAA.
