* Two V.35 interfaces are available on the MPDM: option 1 allows the DTE to control the DTR lead; option 2 maintains the DTR
lead high at all times. Use option 2 if an automatic calling unit, or a DTE that cannot control the DTR, is involved in the connection.
** Can be provisioned with or without an RS-366 interface.
