! ABSTRACT:
!
! Transport Interface Routines: takes a CCB and, based on the function/
! modifier codes, routes it to a processing routine. Some of the func-
! tions require no preprocessing; the function handler is called direct-
! ly. Other routines require preprocessing or are handled entirely in
! this module; all Network Management interface routines are contained
! here.

! ENVIRONMENT: MCB

! AUTHOR: L. Webber , CREATION DATE: 31-Jul-79
!
! MODIFIED BY:
!
! L. Webber, 31-Jul-79 : VERSION 01

!
! 1.24 L. Webber, 3-Jun-81

! codes in the TLI interface).
! Modify all buffer releases to use $MCB_RETURN_CCB_AND_BUFFER.
!
! 1.25 L. Webber, 9-Jun-81
! Fix glitch in DLL_RTN which was always releasing an input CCB, no
! matter whom it belonged to.
!
! 1.26 L. Webber, 25-Jun-81
! Add DLL_RTN processing of "uncounted" message type (used at present
! only for sending "line down" DC's).
!
! 1.27 A. Peckham, 16-Apr-82
