MLX Voice and Modem Data 5
This type of analog data station includes an MLX telephone in addition to the DTE
and modem (see Figure 5-3
). The modem connects to the MLX telephone through
the T/R interface of the Multi-Function Module (MFM), which is installed in the
MLX telephone. The telephone connects to the control unit through an MLX
extension jack. The communication capabilities of the MLX telephone and data
station can be used simultaneously.

ISDN Terminal Adapter Data Stations 5
An ISDN terminal adapter data station uses an ISDN terminal adapter as its DCE
to send and receive data and connects to a digital extension jack (MLX port) on
the control unit. If PRI, NI-1 BRI, or T1 Switched 56 facilities (including T1-Tie
trunks using T1 Switched 56 service) are assigned to the MLX port, that port may
be configured as a 1B Data or 2B Data port. In a 1B configuration, only one of the
assigned B-channels is used by the ISDN terminal adapter data station. The 2B
configuration allows the simultaneous use of both B-channels.WPS
