Nortel DMS-100 Enhanced 911 Direct Access to ALI Controller Table (E911ALI) |
Table Name
Enhanced 911 Direct Access to ALI Controller
Functional Description of Table E911ALI
Table E911ALI contains one entry for each Public Safety Answering Point (PSAP) in the tandem that requires the Automatic Location Identification (ALI) interface. The key to this table is the PSAP name (field PSAPNAME), as defined in table E911PSAP.
This table implements an interface between a DMS-100 switch that serves as an E911 tandem with external 911 equipment, and a previous connection to an Automatic Number Identification (ANI) concentrator. This interface is asynchronous, with ASCII data links located between the Multi-Protocol Controller (MPC) card on the DMS switch and ALI data links connected to an ALI controller. This interface was originally designed specifically for the AT&T ALI controller, which is typically connected to the AT&T Data Management System. The "E911 Direct Access to ALI Database" and "E911 Wireless Interface" features have expanded the interface to support other ALI controllers.
Datafill Sequence & Size
The following tables must be datafilled after table E911ALI:

Table E911ALI Field Descriptions
Field Subfield Entry Explanation and Action
----------------------------------------------------------------------------------------------
PSAPNAME See Subfield Public Safety Answering Point Name Key
This field consists of subfield PSAPNAME.
This is the key to the table.
PSAPNAME Alphanumeric Public Safety Answering Point Name
(1 to 16 characters) Enter the PSAP name. This entry must
correspond to an entry in table E911PSAP.
----------------------------------------------------------------------------------------------
PSAPNUM 0 to 999 Public Safety Answering Point Number
Enter the number of the PSAP receiving ALI
service. Individual positions are numbered
within the PSAP. This value must be
with datafill in the ALI system
computer, and with the values entered when
assigning the ALI option to individual
lines.
----------------------------------------------------------------------------------------------
IFTYPE ATT911AS, OPN911AS, Interface Type
ENH911AS, WLS911 Enter the type of interface to the ALI
system computer. This value must
correspond to the MPC application name
entered in table MPCFASTA.
----------------------------------------------------------------------------------------------
LSETIDX 0 to 15 Link Set Index
This number corresponds to the number of
the MPC linkset defined in table MPCLSET
for use by the data links serving this
PSAP. Each unique index specifies a unique
instance of an ALI interface between the
AT&T database and the ALI controller.
