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.

Datafill Sequence and Implications
Table MTAMDRVE must be datafilled before table MTAVERT.
Table Size
0 to 1,024 tuples.
Store for table MTAVERT is dynamically allocated.
Datafill
The following table lists datafill for table MTAVERT.

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".
----------------------------------------------------------------------------------------------
-End-
SELECTOR = E
If the entry in subfield SELECTOR is E, datafill refinements EHORIZ and EHORZGRP as described below.
----------------------------------------------------------------------------------------------
SELECTOR = E Field Descriptions
Field Subfield Entry Explanation and Action
----------------------------------------------------------------------------------------------
EHORIZ 0 to 127 Extended Metallic Test Access Horizontal Connection
Enter the horizontal connection on the MTA to
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
vertical connection is connected.
----------------------------------------------------------------------------------------------
-End-
SELECTOR = L or O
If the entry in subfield SELECTOR is L or O, datafill refinement LINEMOD as described below.
----------------------------------------------------------------------------------------------
SELECTOR = L or O Field Descriptions
Field Subfield Entry Explanation and Action
----------------------------------------------------------------------------------------------
LINEMOD See Subfields Line Module
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.
---------------------------------------------------------------------------------------------
-End-
SELECTOR = T
If the entry in subfield SELECTOR is T (for licensee use only), datafill refinements TMTYPES and TMNO as described below.
----------------------------------------------------------------------------------------------
SELECTOR = T Field Descriptions
Field Subfield Entry Explanation and Action
----------------------------------------------------------------------------------------------
TMTYPES Alphanumeric Trunk Module Types
(1 to 3 Enter the TM type. This field is for licensee
characters) use only.
TMNO 0 to 511 Trunk Module Number
Enter the number of the TM. This field is for
licensee use only.
