Introduction

The M5317TX and M5317TDX BRI Terminals are for use in North America.
The CustomNet ISDN Handset is the same telephone without NI-1 Signaling
or Meridian 1 voice operation, and is for use in Australia.
M5317TDX telephones and CustomNet ISDN Handsets are connected to the
ISDN BRI (Basic Rate Interface) Service at the "S" (or "T") interface. The
M5317TX and M5317TDX are identical except the M5317TDX has the Data
Option installed on it.
Meridian Feature Transparency (MFT), National ISDN-1 Signaling (NI-1),
and Meridian 1 (Mer1) protocols are supported for voice. Circuit-switched
data is only supported in NI-1 Signaling.
A-law or µ-law Pulse Code Modulation (PCM) voice capability is supported
on either the B1 or the B2 channel.
Circuit-switched data calls are supported using T-link or V.120 protocol, and
packet-switched data calls are supported using X.25 (D-channel) protocol.
