About this document
The following section describes the Multimedia Applications Server Interface, 
and provides instructions on how to set it up, including administration and 
monitoring. It also includes a section on troubleshooting.
You need to use both the DEFINITY system administration terminal (SAT) and 
the MMCX administration terminal to administer MASI. This document describes 
what you need to do at the DEFINITY SAT. It also occasionally mentions 
administration that you must do at the MMCX administration terminal. For more 
detailed MMCX information, see the MMCX Technical Reference. 
List of terms
This is a list of terms that are specific to MASI, or that have meanings in the 
context of MASI that are not standard. 
nchgmasi — The command you use to administer MASI at the MMCX 
administration terminal. 
nInterserver — Connections between MMCX terminals on different 
MMCX servers/nodes.
nMASI domain — A MASI domain consists of a DEFINITY system and 
one or more MASI nodes that share the same dial plan. That is, the 
extension numbers on the MMCX are known to the DEFINITY, and fit in 
the DEFINITY dial plan.
nMASI interworking — MASI interworking refers to the completion of a 
voice connection within a DEFINITY system, involving at least one MASI 
terminal and a MASI path. 
nMASI link — The connection between the MMCX and the DEFINITY 
ECS. 
nMASI node — A single MMCX server. You may connect more than one 
MASI node to a DEFINITY system. Each node has a separate number. This 
node number needs to be consistent whenever referring to a specific 
MMCX server. 
nMASI non-interworking — MASI non-interworking refers to the 
completion of a call by MMCX, not involving a MASI path.
nMASI path — The ISDN B-channels between MMCX and DEFINITY 
ECS in a MASI environment. Paths are used for voice and data connections 
between DEFINITY ECS and MMCX.
nMASI signaling link — ISDN D-channel used to transport a new ISO 
protocol called the MASI protocol between the DEFINITY ECS and the 
MMCX.

nMASI terminal — The DEFINITY system representation of MMCX 
terminals in a MASI environment. 
nMMCX interface — PRI interface for connecting an MMCX server to 
other public, private or WAN switching systems or equipment that is part 
of the public network. Similar to a DEFINITY trunk group. These may 
include non-MASI trunks connecting the DEFINITY ECS and the MMCX.
nMMCX trunk — The DEFINITY system representation of trunk or network 
facilities terminating on MMCX. For purposes of MASI, they are called 
“interfaces.” 
Planning for MASI
Before you start to administer MASI, you should make a plan for how to do it. 
Among the configurations on the following pages, there is probably one that 
matches the configuration of your system fairly closely. You might want to either 
write on these pages, or draw up your own configuration. It may help you if you 
have already determined trunk group and signaling group numbers, unused 
extensions, and so on. The following are things you need to consider: 
nEstablish the dial plan on the MMCX to agree with that of the DEFINITY 
ECS. If you use Universal Dial Plan and MMCX, you may need to make 
adjustments for the MMCX dial plan. 
nFind unused extensions and trunk group numbers. You need:
— one trunk group number for each ISDN-PRI connection to the 
MMCX
— one signaling group number for each MASI node and an unused 
DEFINITY extension for the signaling group
— one unused DEFINITY extension for the Near-End Path 
Termination number for all MASI Paths to this ECS. You can use 
the same number for all MASI nodes in the domain.
— two unused MMCX extensions for the nearpath and tscnum 
arguments to the 
chgmasi command. This is the command you use 
to administer MASI on the MMCX.

MASI configurations
There are several ways to set up combinations of MASI nodes and DEFINITY 
servers.The following figures depict several possible configurations. 
Figure 5. MASI domain of one DEFINITY ECS and one MMCX
The parts of this drawing, for MASI, are as follows:
nTrunk 1 — This is any type of trunk connection to the public network. 
nTrunk 2 — This is the link between the DEFINITY ECS and the MMCX, 
and requires a TN464C or later DS1 circuit pack. You administer this link 
as an ISDN-PRI trunk group, a MASI path and an NCA-TSC. 
nI1 and I2 — These are MMCX interfaces to destinations other than 
DEFINITY ECS. Administer as MASI trunks.
nE1 and E2 — Endpoints (terminals) belonging to the MMCX. Administer 
as MASI terminals. 
nMMCX — Determine a node number for each MMCX server. This can be 
any number from 1–15. Once established, DEFINITY ECS informs the 
MMCX of its node number.
nS1 — DEFINITY station.

How to administer MASI
This section discusses the administration required to make MASI work. You 
perform most of this administration from the DEFINITY administration terminal. 
However, there are a few things you must do at the MMCX administration 
terminal. This section sometimes refers to the 
chgmasi command. This is the 
command you use to administer MASI parameters on the MMCX. For more 
information about using the chgmasi command, refer to your MMCX Technical 
Reference. 
Step 1 — Establish customer options (Lucent 
Technologies)
A Lucent Technologies representative must activate MASI using the 
System-Parameters Customer-Options form. The representative should also verify 
that ISDN-PRI (G3r configurations) or ISDN-PRI over PACCON (G3si/csi 
configurations), and AAR/ARS are enabled. 
On the MMCX, MASI must be enabled using the 
chgmasi command.
Step 2 — Establish maintenance parameters 
and alarming options (Lucent Technologies) 
Ensure that the Maintenance-Related System Parameters form, Packet Bus 
Activated field = y. 
Using the 
set options command (Lucent Technologies init or inads logins only), 
set MASI alarming options. For more information, see DEFINITY ECS 
Maintenance for the appropriate model. 
Step 3 — Establish the physical connection 
Establish the physical connection between the DEFINITY ECS and the MMCX. 
For more information about installing the cables, see Installation for Adjuncts and 
Peripherals.

Step 4 — Administer circuit pack
Using the DS1 Circuit Pack form, verify that the DS1 circuit pack you use to 
establish the MASI link is administered as follows:
nBit Rate = 1.544
nLine Coding = b8zs
nLine Compensation = 1
nSignaling Mode = isdn-pri
nInterface = network
nCountry Protocol = 1
nProtocol Version = a
Step 5 — Administer a signaling group
For each MASI node, you need to establish a unique signaling group. Use the 
command
 add signaling-group xxx to access the Signaling Group form. 
Screen 1. Signaling Group Form (Page 1 of 5)
For each link, establish a Non-Call Associated Temporary Signaling Connection 
(NCA-TSC) with the following attributes:
nAssociated Signaling — MASI requires Facility Associated Signaling, so 
this field must be set to y. 
nPrimary D-channel — Enter a 6- to 7-character port number associated 
with the DS1 Interface circuit pack port. The port address of the PRI that 
carries D-channel signaling.
The port number is used to assign the primary D-channel in the Signaling 
Group. For 24-channel facilities, the 24th port is assigned as the D-channel. 
For 32-channel facilities, the 16th port is assigned as the D-channel.
nMax Number of NCA TSC — For MASI, this must be 1.
nMax number of CA TSC — Leave the default of 0.
nTrunk Group For NCA TSC — This can be left blank. 
nTrunk Group for Channel Selection — This can be left blank. 
                                                              Page 1 of 5

Screen 2. Administered NCA TSC Assignment page of the Signaling Group form
nService/Feature — Leave blank.
nAs-needed Inactivity Time-out (min) — This field only applies to 
as-needed NCA-TSCs. Since MASI requires a permanent connection, 
leave blank.
nTSC Index — This display-only field specifies the administered 
NCA-TSCs assigned. 
nLocal Ext — Enter a valid, unassigned DEFINITY ECS extension. This 
extension does not need a port assignment and does not need to correspond 
to any other administration. 
nEnabled — Enter
\ to enable the administered NCA-TSC. You may want 
to wait to enable this link until all other administration is in place. If this is 
y, DEFINITY ECS attempts to establish the connection as soon as you 
submit the form. This may cause your system to alarm, if other 
administration is not finished. 
nEstablish — Used to indicate the strategy for establishing this 
administered NCA-TSC. Enter permanent for MASI. 
nDest. Digits — A valid MMCX extension. This must correspond to the 
value of the tscnum argument to the 
chgmasi command. 
NOTE:
These digits are sent as entered to the destination MMCX; no routing 
or other digit manipulation is performed.

nAppl. — Specifies the application this administered NCA-TSC is going to 
be used for. Enter masi.
nMachine ID — Used to indicate the MASI node to which this administered 
NCA-TSC is connected. This number should be the same as the MASI 
node number found on other forms. 
How to list TSCs or determine status of the TSC 
To determine which TSCs are designated for MASI, use the 
list masi tsc 
command. 
Screen 3. MASI Temporary Signaling Connections (TSC) Display
This command displays the following:
nSig Grp — The number of the signaling group to which this TSC belongs
nPrimary D-Channel — Port location of the Primary D-channel
nTSC Index — The number of the MASI TSC within the signaling group 
nLocal Ext. — DEFINITY extension associated with the TSC
nEnabled — Indicates the state of the connection - enabled (y/n)
nEstablished — Value of established flag (as-needed/permanent)
nDest. Digits — The MMCX extension that indicates the TSC destination 
nMach. ID — MASI node number 
Once you establish and enable the signaling group, you need to verify that it is 
active. Use the command 
status signaling-group signaling-group# or status 
tsc-administered
 signaling-group# [/tsc-index] [print] to determine if the link 
is active.
