server no long er c ontrols the telep hone line, you c an p lac e c alls from the 
telep hone attac hed  to the telep hone line. 
If you rec eive an inc oming  c all on your sep arate telep hone line while that 
line is c ontrolled  b y the DEFINITY server, that c aller will hear either ring ing  
(if you have c all waiting  on that line) or a b usy sig nal. If you have c all 
waiting , you c an answer the inc oming  c all as you would  answer any other 
c all waiting  c all. 
For the telec ommuter c onfig uration, you must have a sep arate telep hone 
line availab le at your remote loc ation. You d o not need  an H.323 PC aud io 
ap p lic ation suc h as Mic rosoft NetMeeting  3.0x.

nStand-alone H.323 Configuration (Voice over IP
The stand -alone H.323 c onfig uration enab les users to p lac e and  rec eive 
c alls via an H.323 V2-c omp liant aud io ap p lic ation, suc h as Mic rosoft 
NetMeeting  3.0x, running on a PC that is c onnec ted to DEFINITY ECS over 
an IP network. Sinc e this c onfig uration offers limited  c all-hand ling  
c ap abilities, the stand -alone H.323 c onfig uration is not rec ommend ed . 
Adding a DEFINITY IP Softphone 
DEFINITY IP Softphones enable the end user to control telephone calls directly 
from a personal computer (PC). An end user can log into your company’s 
DEFINITY server remotely and make and receive telephone calls from the 
telephone extension. 
DEFINITY IP Softphone supports the following two configurations: 
nRoad-warrior application 
You typic ally use this c onfig uration for lap top  users who are travelling . In 
this c onfig uration, the PC LAN c onnec tion c arries b oth the c all c ontrol 
sig naling  and  the voic e path. Bec ause voic e c alls are routed  over the 
c onnec tion to the PC, you’ll need  an H.323 v2 PC aud io ap p lic ation suc h 
as Mic rosoft ®  NetMeeting  ®  as well as a head set c onnec ted  to the PC to 
sp eak and  hear sound s.
nTelecommuter application or CentreVu IP agent 
For the telec ommuter or CentreVu IP c onfig uration, you make two sep arate 
c onnec tions to the DEFINITY server. The sig naling  p ath is c arried  over an 
IP network and  the voic e p ath is c arried  over the stand ard  c irc uit-switc hed  
telep hone network (PSTN). Sinc e you are using  a p hone for aud io, you d o 
not need  an H.323 PC aud io ap p lic ation. 
The telec ommuter c onfig uration uses the DEFINITY IP Softp hone interfac e 
(on the user’s PC) and  a stand ard  p hone. The CentreVu IP ag ent 
c onfig uration uses the CentreVu IP Agent interfac e (on the ag ent’s PC) 
and  a c all c enter p hone, suc h as a CallMaster. 
Before you start 
Be sure that your system has been enabled to use IP Softphones. Display the 
System Parameters Customer-Options screen and verify the following field 
settings:
nMaximum H.323 Stations is greater than 0 
nMaximum IP Softphones is greater than 0 
nIP Stations field is y

Once you’re finished administering your DEFINITY system, you need to install the 
IP Softphone software on each user’s PC. If you are using the road-warrior 
configuration, you also need to install an H.323 v2 compliant audio software 
application, such as Microsoft NetMeeting.
Instructions for adding a road-warrior application 
You can use the road-warrior application when you have only a single telephone 
line available to access the DEFINITY system over the IP network.
Let’s add a road-warrior application at extension 3001. You have to actually 
administer two extensions for each road-warrior application, so we will first add an 
H.323 extension at 3000. 
To assign an H.323 extension, complete the following steps: 
1. Type add station 3000 and press RETURN. 
The Station
 screen appears. 
2. In the Type field, enter H.323. 
3. In the Port field, enter x. 
4. Press ENTER to save your work. 
Now, you need to administer the phone (DCP) extension. To do so, complete the 
following steps: 
1. Type add station 3001 and press RETURN.

IP Support Hardware
TN799/TN799B: Control LAN (C-LAN) Interface
The TN799/TN799B Control LAN Interface simplifies the connections between 
adjunct equipment and DEFINITY. It provides TCP/IP connectivity over Ethernet 
or PPP (Point to Point Protocol) connections to applications, such as CMS Call 
Center, INTUITY™, AUDIX
®, and DCS. The TN799B is required to support the

TN802B IP Interface operating in MedPro mode for H.323 functionality. The 
TN799/TN799B is also required to support ATM interfaces and WAN PNC on 
DEFINITY R7 or later.
The TN799/TN799B does not support BX.25 connectivity on the R8 or later csi 
platform. On the other platforms, TN765 Processor Interface and TN577 Packet 
Gateway circuit packs provide BX.25 connectivity for existing customers as well as 
TCP/IP service.
The TN799B C-LAN pack provides connectionless UDP sockets for IP solutions 
support, variable length PING and Traceroute. The pack will also support 500 
remote sockets, while current packs support 220.
The TN799 circuit pack is available with R7r, R7si and R7csi and the TN799B C-
LAN circuit pack is available with R8r, R8si, and R8csi.
The TN799 supports the 
traceroute and netstat network testing commands 
starting in R8.
TN802/TN802B Medpro: (IP Interface Assembly)
The TN802 Internet Protocol Interface circuit pack supports voice and fax calls 
from the DEFINITY ECS across a corporate intranet or the Internet. The IP 
trunking software runs on an embedded PC operating under Windows NT. The 
TN802B supports IP Solutions including IP Trunking and MedPro (H.323) with IP 
SoftPhones.
It is implemented using the TN802/TN802B IP Interface, which is a Windows NT 
server that resides on the IP Interface circuit pack inside the DEFINITY ECS. The 
TN802B IP Interface operates in two modes: IP Trunk, available with Release 7, 
and Media Processor (MedPro/H.323), available with Release 8. The TN802B is 
backwards compatible and defaults to IP Trunk mode. To use it in MedPro mode 
you activate it through administration to take full advantage of all the R8 IP 
Solutions features. You also must install a new TN799B C-LAN circuit pack. 
C-LAN Connectivity Changes and Enhancements
Changes to reduce the number of IP routes
1. The change in R8 to make automatic subnet routing always enabled means 
that fewer IP routes need to be defined. In R7, if automatic subnet routing 
is disabled, an explicit IP route needs to be defined between every pair 
nodes on the subnet that you want to inter-communicate. In R8, automatic 
subnet routing is always enabled so you never need to define an explicit IP 
route within a subnet.
2. In R7, there was no default gateway unless it was explicitly defined in an IP 
route using the default node name as the Destination. With no default 
gateway, any communication with a remote node on another subnet 
required two IP routes. One IP route was needed from the C-LAN

(identified as the gateway on the IP route screen) to a router (identified as 
the destination on the IP route screen). Then the router is identified as the 
gateway and the remote node as the destination in another IP route. In R8, 
you can specify a default gateway on the IP Interfaces screen for each IP 
interface. Then any messages sent to a node on a different subnet will be 
automatically sent to this gateway. This eliminates the need to create the 
two IP routes needed in R7.
New Screens
A new screen, IP Interfaces, defines the properties of an interface between a 
DEFINITY system and an IP network.

When to use IP routes
You need to define host and/or network IP routes only in special cases when 
default gateways are not defined or when you want to limit communication 
between nodes. This section describes the network configurations that require 
explicit IP routes.
There are two type of IP routes — 
host and network. The following table 
summarizes when you would use each type:
NOTE:
The endpoint nodes are on the same subnet if the following three conditions 
are met:
nthe end p oints are on the same p hysic al sub network
nthe Sub net Mask field  is assig ned  the same value on the IP 
Interfac e sc reens for the two end p oint nodes 
nthe network +  subnet p ortions of the IP ad d resses (as determined  
b y the sub net mask) are the same
To set up an IP route, enter the node names for the destination and the gateway, 
and enter the slot location of the C-LAN on the local switch. Enter host or 
network in the Route Type filed. For either type, the destination and gateway 
node names and their associated IP addresses must be specified on the Node 
Names screen. An IP address for a network has the network ID in the network 
portion and 0 in the host portion. For example, 192.168.1.0 is the network address 
for the 192.168.1 network. 
When a network is subnetted, and you want to set up a network IP route to a 
subnetwork, the IP address of the subnetwork is the first address in that 
subnetwork, which has all 0’s for the host portion of the address. For example, the 
subnet mask formed by using 2 bits of the host portion of a Class C address is 
255.255.255.192 (1100000 = 192). For the 192.168.1 network, this subnet mask When IP Routes are Needed:
Connection 
Ty p e
Host IP Routes Network IP Routes
Ethernet You want the local host to 
communicate with only the 
specified host on a remote 
subnet — endpoints are on 
different subnets and no 
default gateway is defined 
for the local node.You want the local host to 
communicate with any host 
on the specified remote 
subnet but not with hosts on 
other subnets — endpoints 
are on different subnets and 
no default gateway is defined 
for the local node.
PPP There are one or more 
intermediate nodes between 
endpoints.Network IP routes are not 
used with ppp connections.
