† TT stands for trunk type.

Notes:

1.Dedicated circuits are provided via permanent switched connections (PSC) on the System 75 and Generic 1; and dedicated switched connections (DSC) on the System 85 (R2V3 and R2V4) and Generic 2. DSC amd PSC connections cannot be used together.

2.On the System 85 or Generic 2, trunk type DMI does not allow subnet trunking to be used with AAR/ARS. In addition, with DMI, no modem pooling is allowed and the bearer capability class must be set appropriately.

3.If an MPDM is used, it must be installed with a V.35 interface and an ACCUNET SW56 modification kit.

4.The System 75 and Generic 1 PSC require that a SW56 DSU be used with the D4 channel bank. System 85 (R2V4) and Generic 2 DSC allow either a SW56 DSU or a private line DSU.
