Single In-Line Telephone Line Interfaces for Europe Description
Xecom's XE10X0 Single In-Line telephone interfaces offer complete, highly compact telephone interfaces for Europe, Japan and North America. The XE10X0 family includes six models. Each meets the regulatory requirements for connection to the telephone network in one or more countries. A common single in-line package provides maximum flexibility in component placement and permits world-wide connectivity from one, simple circuit board layout. XE1030 complies with the requirements of several European countries including the United Kingdom. It supplies 3750 volts isolation from the telephone line and has BABT, UL and CSA approval. XE1040 provides the circuitry to connect to the German telephone network. It includes the 16 Khz Meter Tone Filter and 3750 volts isolation. The XE1040 also has BABT approval. XE1050 meets French telephone network requirements. It includes BABT approval, over current protection on both tip and ring, and provides 3750 volt isolation. XE1060 meets telecom requirements for North America and Japan. It provides 1500 volts isolation from the telephone network and is FCC part 68 compliant. XE1070 provides a connection to the Italian telephone network. XE1070 includes BABT approval and provides 3750 volt isolation. XE1080 connects to the Spanish telephone network. XE1080 includes BABT approval and provides 3750 volt isolation.

DESCRIPTION
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. 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. /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. 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. T1 provides half of the differential input/output connection to the secondary side of the internal telephone line transformer. T2 provides half of the differential input/output connection to the secondary side of the internal telephone line transformer. 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. 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. 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.
