Sangoma E1 / T1 Line Tapping System

As requirements for security, customer service and legal responsibilities have increased, it has become important to be able to monitor and record telephone conversations.

Sangoma?s T1/E1 tapping solution is a high performance, robust and inexpensive toolkit that gives you complete access to the T1/E1 voice and signaling interfaces. Based on the popular A102, A104 and A108 AFT cards, the system supports the tapping of one, two and four T1/E1 lines per card respectively.

A convenient Tap Connection Adapter is available, which allows the data transport line to be hard wired with strain relief. The tapping connections are then simply connected to the RJ45 connectors provided.

Both normal impedance and high impedance (high sensitivity) modes are supported.


The Sangoma Line Tapping Solution is comprised physically of an A102 (dual port) A104 (quad port) or A108 (octal port) T1/E1 card, standard cabling, and a PN 633 Tap Connection Adapter. The lines to be tapped are hard wired into the Tap Connection Adapter. Straight cables are connected between the Tap Connection Adapter and a pair of ports on the T1/E1 card, allowing both sides of the line to be monitored simultaneously.

The system can be used in both standard impedance and high impedance modes, high impedance being used to ensure that no accidental short of the monitoring lines will affect the flow of T1/E1 traffic.

Technical Specifications

  • Supports tapping from one to four T1/E1 ports per card.
  • Includes low-level API under Windows and Linux, which supports access to the G.711 data streams directly, as well as access to D channel HDLC traffic for interpretation of the PRI control packets.
  • Both PRI and RBS-type signaling are supported.
  • Line impedance: 100/120 ohms standard T1/E1 or 1200 ohms high impedance.
  • Optional board-based DSP for DTMF detection and tone recognition.
  • Highly-optimized driver allows tapping of up to 16 spans on a single PC with minimal system load.
  • Connection to Tap Connection Adapter uses a standard straight RJ45 cable.
  • Tapping solution available in PCI (5 V), PCI-X (3.3 V), and PCI-Express form factors.
  • Card dimensions: 2U height form factor: 290 mm x 55 mm for use in a 2U chassis.
