IP Solutions
DEFINITY ECS IP Solutions provide TCP/IP connectivity for two types of trunks and 
three types of IP Softphones. On DEFINITY ECS, 
IP Solutions use the TN802B IP 
Interface assembly, which includes a Windows NT server that resides on the 
TN802B circuit pack inside the DEFINITY ECS. The TN802B IP Interface, 
introduced in Release 8, operates in either the IP Trunk mode (for ITS-E 
connections) or in the MedPro mode (for H.323 trunk connections). The TN802 
IP-Interface, introduced in Release 7, operates only in the IP Trunk mode. The 
MedPro mode requires the TN802B plus the new TN799B C-LAN circuit pack. 
The following table summarizes the IP Solutions configurations and the circuit 
packs and software used with each.
TCP/IP-Connected Trunks
IP-connected trunks allow trunk groups to be defined as tie lines between 
switches over a virtual private network (VPN).
Trunks using IP connectivity provide cost-reduction and simplified management. 
Benefits include a reduction in long distance voice and fax expenses, facilitation of 
global communications, full-function networks with data and voice convergence, 
and network optimization by using the existing network resources. 
H.323 Trunk
The TN802B IP Interface in Medpro mode enables H.323 trunk service using IP 
connectivity between two DEFINITY ECS systems. H.323 trunk groups can be 
configured as DEFINITY-specific tie trunks supporting ISDN trunk features such 
as DCS+ and QSIG, or as generic tie trunks permitting interconnection with other  IP SolutionsCircuit Pack Requirements Software Requirements

vendors’ H.323 v2-compliant switches, or as direct-inward-dial (DID) type of 
“public” trunk providing access to the switch for unregistered users. A variety of 
signaling options can be chosen by the system administrator.
IP Trunk
The IP Trunk mode will typically be chosen for interoperability with existing TN802 
(as opposed to the TN802B) IP Interface circuit packs. IP Trunk can be used only 
between two DEFINITY switches. Each IP Interface circuit pack in IP Trunk mode 
provides a basic twelve-port package that can be expanded up to a total of 30 
ports.
H.323 Trunk Administration
This section describes the administration steps needed to setup H.323 trunks. 
The first subsection covers the enabling administration that needs to be in place 
before the trunk administration can be done. The second subsection gives a 
summary of the H.323 trunk administration.  Detailed procedural steps and the 
screens used for this administration are given in 
DEFINITY ECS Administration 
for Network Connectivity
, 555-233-504.
Screen fields not mentioned here are administered as in previous releases. 
Enabling Administration
Before you can administer an H.323 trunk, a few customer options and circuit 
pack parameters need to be properly set. In addition, there are some optional 
maintenance and IP parameters that can be administered. These enabling 
settings are summarized here.
Optional Features (System Parameters Customer Options)
The Optional Features screen must be administered by the init login. Open the 
screen with the change command (ch sys cu) and set the following fields:
page 1
nG3 Version = V8 
nMaximum H.323 Trunks = number purchased; must be greater than 0.
page 3
nH.323 Trunks? = y
nISDN-PRI? = y

Circuit Pack
The C-LAN and IP Interface assembly circuit packs must be administered on the 
Circuit Pack screen. Open the Circuit Pack screen with the change command (ch 
ci) and enter the board codes in available port slots:
nC-LAN
nCode = TN799
nSfx = B
nName = C-LAN
IP Interface assembly — enter in a slot with at least two empty slot before it
nCode = TN802
nSfx = B
nName = MAPD Board {entered automatically by system}
The two slots immediately before this slot are automatically populated as follows:
nCode = DSMAPD {displays automatically}
Change DSMAPD to MEDPRO {the IP Interface board defaults to the IP Trunk 
mode, which is specified by the DSMAPD in this field. Changing this field to 
MEDPRO changes the board’s mode to MEDPRO}
nSfx = {blank}
nName = Reserved - IP {displays automatically}
Maintenance-Related System Parameters
Four parameters on the Maintenance-Related System Parameters screen set 
threshold values for network performance: 
page 4
nRoundtrip Propagation Delay (sec)  High: 800_  Low: 400_
nPacket Loss (%)  High: 40__ Low: 15__
nPing Test Interval (sec): 20 
nPings per Measurement Interval: 10 
These parameters have no effect unless the bypass function is activated on the 
Signaling Group screen. If the bypass function is activated for a signaling group, 
ongoing measurements of network activity collected by the system are compared 
with these values. If the values of these parameters are exceeded by the current 
measurements, the bypass function terminates further use of the network path 
associated with the signaling group. The following actions are taken when 
thresholds are exceeded:
nexisting calls are maintained
nincoming calls are allowed

noutgoing calls are blocked on this signaling group; if so administered, 
blocked calls are diverted to alternate routes (either IP or circuits) as 
determined by the administered routing patterns
You can use the default values set for these parameters, or you can change them 
to fit the needs of your network. The Maintenance-Related System Parameters 
screen can be administered by the 
init, inads, or craft logins. Open the screen with 
the change command (ch sys ma).
IP Parameters
The IP Parameters screen allows you to specify the type of codec used for voice 
compression/decompression. The difference between codecs is in the 
compression algorithm: some codecs compress the voice data more than others. 
A greater degree of compression results in lower bandwidth requirements on the 
network, but may also introduce transmission delays and lower voice quality. The 
default codec is set for G711. This can be changed to one of four others if the 
G711 does not meet your desired voice-quality/bandwidth tradeoff specification. 
Also, if the far-end switch is a not a DEFINTIY ECS, you may need to change the 
codec to match one that is supported by that switch.
The order in which the codecs are listed on this screen is the order of preference 
of usage. A trunk call between two DEFINITY switches will be set up to use the 
first common codec listed on the two IP Parameters screens.
You can also use the Audio IP port number range field to specify a block of port 
numbers to be used for audio connections. Then, if your network is equipped with 
the appropriate data filtering devices, audio data can be segregated from other 
data traffic to improve quality of service.
Open the screen with the change command (ch ip-p) and set the following fields:
nCodec type = {enter as many of the following types as supported by this 
switch, in the preferred order of usage — G711A, G711Mu, G723-6.3k, 
G723-5.3k, G.729A}. Refer to the following table of bandwidth 
requirements to decide which codecs to administer:
nAudio IP port number range = 
UDP Port Rang e 
Min: 2048 
Max: 65535
Codec Bandwidth Requirement
G711 A-law @ 64Kbps 117.6 Kbps
G711 Mu-law @ 64Kbps 117.6 Kbps
G723 @ 6.3Kbps 31.1 Kbps
G723 @ 5.3Kbps 29.6 Kbps
G729 A-law @ 8Kbps 33.6 Kbps

Network Regions
The Region field on the IP Interfaces screen allows you to set up segregated 
groups of C-LAN and IP Interface (Medpro) resources. This feature can be used in 
a variety of ways. For example, you could use regions to allocate specific C-LAN 
and IP Interface boards to H.323 trunks and others to stations; or you could use 
regions to avoid multimedia traffic over low bandwidth or high-latency network 
links.
DEFINITY Internet Protocol (IP) Softphones
DEFINITY IP® Softphone is a collection of computer telephony integration (CTI) 
applications that enables you to control telephone calls (both incoming and 
outgoing) directly from your personal computer (PC). DEFINITY IP Softphone 
enables you to log into your companys DEFINITY server remotely and make and 
receive telephone calls from the telephone extension. These applications run with 
Microsoft
® Windows® NT Workstation 4.0 or later, Microsoft Windows NT® Server 
4.0 or later, Microsoft Windows 98, and Microsoft Windows 95.
DEFINITY IP Softphones extend the level of DEFINITY services. They turn a PC 
or a laptop into an advanced telephone. DEFINITY IP Softphones allow you to 
send voice and fax from the DEFINITY ECS through an Internet Protocol (IP) 
network to other DEFINITY systems that have this feature. You can place calls, 
take calls, and handle multiple calls on your PC. 
DEFINITY IP Softphones extend DEFINITY multifunction, multiline features 
support to IP-connected endpoints (typically user PCs). With certain exceptions, 
every feature available for wired-endpoint voice calling is available for IP-based 
calling; it supports full internetworking with conventional circuit-switched stations 
and trunks. 
IP Softphone Configurations
DEFINITY IP Softphone supports the following three configurations:
nRoad-Warrior Configuration (Voice over IP
The road -warrior c onfiguration enab les travelers to use the full DEFINITY 
ECS feature set from temp orary remote loc ations anywhere in the world  
(suc h as a hotel room). The road -warrior c onfiguration c onsists of two

over an IP network. The sing le network c onnec tion b etween the PC and 
the DEFINITY ECS c arries two c hannels, one for the sig naling  p ath and  
one for the voic e p ath. DEFINITY IP Softp hone hand les the c all sig naling 
and  an H.323 V2-c omplilant aud io app lic ation, suc h as Mic rosoft 
NetMeeting  3.0x, hand les the voic e c ommunic ations. You p lac e and  
rec eive c alls via DEFINITY IP Softp hone and  use the H.323 PC aud io 
ap p lic ation to sp eak to and  hear the other p arties on c alls via a head set 
c onnec ted  to your PC or a mic rop hone c onnec ted  to (or integ rated  with) 
your PC. The DEFINITY server routes all of your inc oming  and  outg oing  
c alls over the c onnec tion between your PC and  the DEFINITY server. 
In the road -warrior c onfig uration, Mic rosoft NetMeeting has b een 
c onfig ured  to run in the b ac kg round  and  uses only the aud io p ortion of the 
ap p lic ation. The d ata c ollab oration feature of NetMeeting  c an b e used  as 
a stand -alone ap p lic ation, b ut it is d isab led  d uring  a DEFINITY IP 
Softp hone session. 
You c an use an H.323 ap p lic ation other than Mic rosoft NetMeeting 3.0x in 
the road-warrior configuration. However, if you use an H.323 application 
other than Mic rosoft NetMeeting  3.0x, that H.323 ap p lic ation will not run in 
the b ac kg round  like Mic rosoft NetMeeting .
NOTE:
DEFINITY IP Softp hone works with any H.323 Version 2-c omp liant 
ap p lic ation (suc h as Mic rosoft NetMeeting 3.0x) that c an register 
with an E.164 alias.

The telec ommuter c onfig uration of DEFINITY IP Softp hone enab les 
telec ommuters to use the full DEFINITY ECS feature set from home. In this 
c onfig uration, you use two c onnec tions to the DEFINITY server. Over the 
first c onnec tion (via d ial-up  networking  or a network interfac e c ard ), you 
log into the DEFINITY server and  c ontrol all of your inc oming  and  outgoing 
c alls. Over the sec ond  c onnec tion (whic h is a sep arate telep hone line), 
you sp eak to and  hear the other p arties on your c alls. The DEFINITY 
server routes all of your voic e c alls to the sep arate telep hone line, 
enab ling  you to sp eak to and  hear the other p arties via the telep hone 
attac hed  to that line. In effec t, the telep hone ac ts like the hand set on the
