Standards and interfaces

Telesis PX24X , X1 and Stillink support signaling for two-bit R1 line / MFR1 interregister according to ITU-T recommendations. Telesis PX24M, PX24X, and X1 support signaling for MFR1 interregister on analog Type-V E&M interfaces.

R1 signaling E1 and EM interfaces in Telesis systems

Telesis systems have R1 signaling E1 and E&M interfaces to connect to PSTN and private network

Options

The physical interface for single-bit and two-bit signaling is E1 (ITU-T G.703). 120 ohm balanced terminations are supported on any E1. The line code is HDB3 or AMI programmable. CRC4 may be enabled or disabled. Each E1 channel can be programmed as incoming, outgoing, bothway trunk, or unavailable.

Each analog E&M trunk board has four line circuits that satisfy the conditions for Type-V connections. Each port may individually be set to either a two- or four-wire interface by appropriate configuration of the on-the-board jumpers. An additional detector on the M-wire checks the DC feed on the line to detect faulty conditions in far-end equipment. The analog E&M trunk card is available for 600 ohm resistive reference impedance. Each E&M port can be programmed as incoming, outgoing, bothway trunk, or unavailable.

Route, Routeset Configuration, Routing

In a Telesis system, each E&M interface and E1 channel may have its own route number. It is possible to define numerous distinct routes. A given route to a particular destination and its accompanying routes are grouped in a routeset. Each route in a routeset has a priority order. Routing to the next priority alternate route is possible in the event that a route becomes unavailable. The Telesis system realizes routing according to the dialed digits or calling party number.
