Nortel DMS-100 Metallic Test Access Vertical Connection Table (MTAVERT)

Table Name

Metallic Test Access Vertical Connection Table

Functional Description of Table MTAVERT

Table MTAVERT identifies the vertical connectivity to the Metallic Test Access (MTA) matrix.  Two types of vertical connections are allowed, as described below.

Single

A single connection is defined using selectors L, E, T, and O.  Selector L requires the assignment of two vertical connections for the Line Concentrating Devices (LCD).  One is for the first 320 lines; the other is for the remaining lines.  The datafill automatically takes the two vertical connections; one vertical connection is taken as the primary and the other is taken as its mate.  Any attempt to datafill on a vertical that is a mate is denied.  Mate verticals cannot be displayed in table control.

Selectors E, T, and O require the assignment of a single vertical connection for use.  Selector E defines an extended vertical; the MTA Minibar Drivers (MTAM) on this vertical must all be located at the host (field SITE).  Selector T specifies that the vertical is connected to a Trunk Module (TM) Peripheral Module (PM).  Selector O is for LCDs that require only one vertical for test access.

Note:  Selector T is reserved for a special market segment (Austria) and is not available for general usage.

Multiple

The vertical connection is connected to a remote LCD that does not reside on a Subscriber Carrier Module (SCM) and can have multiple or shared appearances of LCDs.  Only selector O can be used, and a maximum of 32 LCDs for each vertical are allowed.

The Figure 1 illustrates single and multiple vertical connections.

Table MTAVERT Field Descriptions

Field       Subfield       Entry               Explanation and Action
----------------------------------------------------------------------------------------------
VERT                       0 to 1,023          Vertical
                                               Enter the Metallic Test Access (MTA) vertical 
					       connection number.

					       If subfield SELECTOR has value "L", and the 
					       entry in field MTACARD has value 2X50AB 
					       (in table MTAMDRVE), the entry in field VERT 
					       must be an even number.  Each Line Module (LM) 
					       requires two vertical connections that must be 
					       adjacent.  The second connection is made 
					       internally to vertical VERT+1.  The odd 
					       numbered vertical can only be used internally.
----------------------------------------------------------------------------------------------
VERTCONN                   See Subfield        Vertical Connection
                                               This field consists of subfield VERTSEL.

            VERTSEL        M or S              Vertical Connection Type Selector
	                                       Enter one of the two types of vertical 
					       connections.

                                               For multiple LCD connections to the 
					       vertical connection, enter "M" and datafill 
					       refinement VERTAREA.  This entry can be used 
					       only if the vertical is connected to a remote 
					       LCD that does not reside on a Subscriber Carrier 
					       Module (SCM), namely Remote Carrier DMS-1 Rural 
					       (RCT), Remote Concentrator SLC-96 (RCS), Remote 
					       Carrier DMS-1 Urban (RCU), and Remote Digital 
					       Terminal (RDT).  Multiple connections are allowed
					       and a vector of up to 32 selectors plus their 
					       refinements can be input.  If less than 32 
					       selectors are required, end the list with a "$" 
					       (dollar sign).

                                               If subfield VERTSEL is set to "M", subfield 
					       SELECTOR can only have a value of "O".

					       For a single Line Concentrating Device (LCD) 
					       connection to the vertical connection, enter 
					       "S" and datafill refinement VERTITEM.  Only a 
					       single connection is allowed and only one 
					       selector and its refinements can be input for 
					       any tuple.  Any selector and its refinements 
					       can be used in this case.

            VERTITEM       See Subfield        Vertical Item
	                                       If the entry in subfield VERSEL is "S", datafill 
					       this refinement.  This field consists of subfield 
					       SELECTOR.

            VERTAREA       See Subfield        Vertical Area
	                                       If the entry in field VERTSEL is "M", datafill 
					       this refinement.  This field consists of subfield 
					       SELECTOR.

            SELECTOR       E, L, O, or T       Selector
                                               Enter one of the four selector types.

					       If the vertical connection is used for an 
					       extended connection, enter "E" and datafill 
					       refinements EHORIZ and EHORZGRP in section 
					       "SELECTOR = E".

					       If the vertical connection is used for a line 
					       module, enter "L" and datafill refinement LINEMOD 
					       in section "SELECTOR = L".  Selector L requires 
					       that two verticals be used.  The datafill 
					       automatically takes the two verticals, one as the 
					       primary and other as its mate.

					       If the vertical connection is used for a RCT or 
					       RCS, enter "O" and datafill refinement LINEMOD 
					       in section "SELECTOR = L".

					       If the vertical connection is used for a RTD,
					       enter either "L" or "O" and datafill refinement 
					       LINEMOD in section "SELECTOR = L".  Up to two 
					       vertical assignments can be made for one or more 
					       RTDs.

					       If the vertical connection is connected to a
					       Trunk Module (TM) Peripheral Module (PM), enter 
					       "T" and datafill refinements TMTYPES and TMNO 
					       (for licensee use only) in section 
					       "SELECTOR = T".

					     which the vertical connection is connected.

            EHORZGRP       0 to 159          Extended Metallic Test Access Horizontal Group
	                                     Enter the horizontal group on the MTA to which the

	                                       This field is identical to field LEN that is 
					       datafilled in other tables.  Field LINEMOD 
					       (and field LEN) defines the physical location 
					       of the equipment that is connected to a 
					       specific telephone line.

                                               Field LINEMOD (and field LEN) consists of 
					       subfields SITE, FRAME, UNIT, DRAWER or LSG, 
					       SHELF, SLOT, and CIRCUIT.

					       If the entry in field SELECTOR is "O", the 
					       field LINEMOD subfields must be set for RCS, 
					       RCT, or RDT only.
