OVERVIEW: DEFINITY GENERIC 2 WITH UNIVERSAL MODULES
CROSS-CONNECT FIELDS
The DEFINITY Generic 2 with universal modules uses System 75 port board technology and has 500
pairs per carrier and 3 carriers per module. This creates significant differences in wall-field design from
that used in System 85 and DEFINITY Generic 2 with traditional modules. See chapter 7, MDF/IDF
Design: DEFINITY Generic 2 with Universal Modules, for more information on wall-field design for
DEFINITY Generic 2 with universal modules.
TERMINALS AND TERMINAL ADJUNCTS
Physical and functional descriptions for prospective customers, account teams, and others who need
specific information on universal terminals and terminal adjuncts for Generic 2 with universal modules
are listed in About This Document under Related Resources.
CONNECTIVITY
Connectivity for DEFINITY Generic 2 with universal modules is similar to that of System 85 and
DEFINITY Generic 2 with traditional modules. A major difference is the use of unshielded M-F B25A
cables to connect the switch to the male-connectorized cross-connect field wherever possible. Previously
installed systems may require M-M A25D connectorized cables. (See figure 1-1, System 85 and
DEFINITY Generic 2 with Traditional Module Connectivity, for a typical connectivity configuration.)
MAJOR COMPONENTS—SINGLE CARRIER MODULE
The single carrier module (SCM) introduces new cabinetry and equipment into the G2 environment:
●
The SCM is designed as a remote module only and cannot support other remote modules.
●
Each SCM can accommodate one to three single carrier port cabinets to support the port complex.
●
The module control is duplicated in a single carrier.
Cabinet Types
The main components of the SCM are the single carrier module control cabinet (SCMCC) and the single
carrier port cabinet (SCPC). A full, four-cabinet SCM stack contains one SCMCC and three SCPCs.
