Number of MedPros 
neededThe following table gives the approximate carried load (CLm), in Erlangs, for m 
MedPro boards installed. Carried loads are shown for a = 22 and 31 audio streams per 
MedPro board, corresponding to having the G.723 or G.729A (a=22) or the G.711 
(a=31) codecs administered.  
Assumptions
This table assumes:
•In columns 2 and 3, the carried loads are calculated assuming an infinite source 
for Grade of Service (GOS) of P001. The carried loads are calculated as an 
average of Erlang B and Erlang C to account for retrials
•In columns 3 and 4, the carried loads are calculated assuming full availability (no 
blocking). Note that the carried load for the full availability case is just the 
number of audio streams times the number of MedPro boards.Number of

Number of C-LANs 
neededThe number of C-LAN circuit packs needed can be estimated as follows:
1  Calculate the C-LAN socket carried load, for c sockets, CLc
2  The number of C-LANs needed is:
# C-LANS = CL
c/448 for infinite source, GOS of P001
# C-LANS = CL
c/508 for “full availability.”
Assumptions
This formula assumes:
•508 is the maximum number of simultaneous TCP/UDP connections per C-LAN.
•448 is the average of Erlang B and Erlang C for GOS = P001 and 508 
connections.
Example Internet Call Center 
A DEFINITY call center with all incoming connections originating as H.323 DID 
endpoints on the Internet. The customer requires 10,000 Busy Hour Calls (BHCs) be 
carried, with a GOS of P001. The average call holding time is 100 seconds and the 
codec is G723.1.
Problem
Calculate the DEFINITY resources required — the number of C-LANs and the 
number of MedPros.
Solution
The average number of C-LAN sockets per call (c), for H.323 endpoints, is 2.
The number of audio streams per MedPro (a), for the G723.1 codec, is 22.
The endpoint carried load is:
10,000(
calls) x 1(CCS holding time per call)/36(CCS per Erlang) = 277.8 Erlangs.
From the MedPro table, 15 MedPro boards are required (rounding up).
Since there are 2 sockets per call (for H.323 endpoints), the socket carried load is 
2x277.8 = 555.6 Erlangs. 
Using the C-LAN formula, 555.6/448 = 2 C-LAN boards are required (rounding 
up).

E C-LAN Installation
This chapter provides instructions for installing and making the physical connections to the circuit packs that are 
new for R7 — the C-LAN (TN799) and the NetPkt (TN794) circuit packs. The C-LAN circuit pack is optional 
for R7 but required for TCP/IP connectivity in all switch models. The NetPkt circuit pack is required for R7 in 
the si model only.
These instructions are also included in the upgrades and installation documents for each switch model. They are 
duplicated here for convenience and completeness.
Overview
Systems in a DCS network are interconnected by both tie trunks (for voice 
communications) and data links (for control and transparent feature information). 
Various DS1 interface circuit packs (including TN464C, TN767C, TN722, and 
TN760) provide the voice-communications interface. For TCP/IP connectivity, the 
data-link interface is provided by a TN799 C-LAN circuit pack. 
The C-LAN handles the data-link signaling information in one of two configurations; 
either 10BaseT ethernet or point-to-point (ppp).
•In the ethernet configuration, the C-LAN passes the signaling information over a 
separate 10BaseT  TCP/IP network, usually via a hub. For this configuration, 
install the C-LAN circuit pack and connect the appropriate pins of the C-LAN I/O 
field to the hub as described below.
•In the ppp configuration, the C-LAN passes the data-link signaling to the DS1 for 
inclusion in the same DS1 bit stream as the DCS voice transmissions. For this 
configuration, install the C-LAN circuit pack; no other connections are needed.
In both configurations, the appropriate DS1 circuit packs must be installed if they are 
not already present.

Install the C-LAN Circuit Pack
The following sections describe the steps for installing the C-LAN circuit pack.
Insert C-LAN Circuit 
PacksTCP/IP connections (10BaseT ethernet or ppp) require a TN799 C-LAN circuit pack. 
Complete the following steps to install these circuit packs.
1  Determine the carrier/slot assignments of the circuit packs to be added. Both 
types of circuit pack can go into any port slot with the following exceptions —
The C-LAN circuit pack cannot be installed in the A carrier for
~the r model
~a duplicated si model
2  Insert the circuit packs into the slots specified in step 1. You do not need to power 
down the cabinet to install a C-LAN circuit pack.
Administer the C-LAN 
Bus Bridge for csi 
modelsFor the csi model only, complete the following steps to administer the Bus Bridge for 
the new C-LAN circuit pack.
Note:If there are 2 C-LAN circuit packs installed in this csi switch, administer 
the Bus Bridge for only one of them.
1  Enter change system-parameters maintenance. 
2  At the bottom of Page 2, enter y in the Packet Intf2 field.
3  Enter the location of the C-LAN circuit pack in the Bus Bridge field (for example, 
01a08 for cabinet 1, carrier A, and slot 8).
4  Enter the port bandwidths or use the defaults in the Pt0, Pt1, and Pt2 Inter-Board 
Link Timeslots fields.
5  Submit the form.
6  Verify that the bus bridge LED is lit on the C-LAN circuit pack. This indicates 
that the packet bus is enabled.
Test the Packet Bus 
and C-LAN Circuit 
PackTo test the packet bus and the TN799 C-LAN circuit pack, the cabinet needs a 
TN771D Maintenance/Test circuit pack. 
1  If there is no TN771D circuit pack in the cabinet, place one in a port slot.
2  Enter test pkt port-network 1 long. For more information about these tests, 
refer to the “test pkt command” section in the maintenance book. 
3  If the TN771D circuit pack was already in the cabinet, leave it there.
4  If you added the TN771D circuit pack to the cabinet in order to test the TN799 
circuit pack, remove it from the cabinet.

The following table shows the relationship between the backplane and the peripheral 
(Amphenol) pinouts, and the RJ45 pinouts on the D8W cable, for the C-LAN circuit 
pack in any port slot.
Wall field connection
Instead of connecting a D8W cable to a hub, you could connect a standard Amphenol 
cable between the peripheral connector and the wall field. In this case, you would 
need to reverse the transmit and receive pairs. The transmit/receive reversal is done 
automatically by a hub.
Other Hardware Upgrades
Upgrades to DEFINITY ECS Release 7 require new processor circuit packs for the 
csi and si models (TN798B and TN790B, respectively) and the NetPkt (TN794) 
circuit pack for the si model.
For the si model upgrading to R7, the NETCON (TN777) and the PACCON (TN778) 
circuit packs must be removed and the NetPkt circuit pack assembly must be 
installed. The NetPkt circuit pack is attached to a TN2400 circuit pack as a double 
circuit pack assembly that is inserted in the NetCon/PacCon slots. The connections 
built into this assembly provide the necessary jumpers between the NETCON and 
PACCON slots.
Refer to the appropriate upgrades document for the procedures to install these circuit 
packs and upgrade the software.Backplane

F IP Trunk Installation and
Administration
This appendix describes the procedures for installing and administering IP Trunk connections 
using the TN802 IP Interface circuit pack or the TN802B IP Interface set for IP Trunk mode. This 
appendix does not cover the TN802B IP Interface set for medpro mode for H.323 trunks — this 
material is covered in Chapter 2.
DEFINITY ECS with Internet Protocol (IP) Trunk allows you to route voice and fax calls over IP networks to 
other DEFINITY ECSs that also have this feature, or to other PBXs (Lucent or non-Lucent) equipped with the 
Internet Telephony Server–Enterprise (ITS-E). The IP Trunk service enables you to reduce long-distance charges 
and gives you added flexibility in routing traffic between sites. IP Trunk is implemented using the TN802 circuit 
pack. 
IP Trunk connections can be used with Release 7 and Release 8 of all three 
DEFINITY ECS switch models — csi, si, and r.
To use the IP Trunk feature, the IP Interface assembly needs to be installed. The IP 
Interface assembly (J58890MA-1 L30) is a 3-slot wide TN802 (R7) or TN802B (R8) 
MAPD circuit pack.
The procedures in this appendix apply to the following software/circuit pack 
configurations:
•R8 with the IP Interface/TN802B in IP Trunk mode
•R8 configured as R7 (bugfix) with the IP Interface/TN802 or TN802B in IP 
Trunk mode
•R7 with the IP Interface/TN802
IP Trunk Installation
For IP Trunk installation procedures, see the upgrades or installation document that is 
appropriate for the switch model. There are five upgrades/installation documents on 
the DEFINITY Documentation Library CD-ROM. See DEFINITY ECS R8.2 
Documentation CD-ROM, 555-233-813.

IP Trunk Administration
This section tells you how to administer the IP Trunk service after all installation procedures are complete. 
Prerequisites
Before you can administer an IP trunk group, you must have one or more TN802 
circuit packs (or TN802B set to IP Trunk mode) and a right-to-use license for the 
number of ports you need. Refer to DEFINITY ECS System Description for 
information on the TN802 circuit pack.
The TN802 circuit pack contains the Windows NT™ operating system. The IP trunk 
software that sends and receives calls over a TCP/IP network resides on this NT 
server. You need to use a Windows NT application called Configuration Manager, 
and your DEFINITY ECS switch administration software to administer IP trunk 
groups.
In order to complete the administration for IP trunks, the following must also be in 
place:
•The TN802 circuit pack must be connected to an Ethernet 10/100 BaseT 
local-area network.
•In order to log on to the NT server on the TN802 circuit pack, a monitor, 
keyboard, and mouse must be connected directly to the circuit pack. 
Alternatively, you can access the NT server remotely via a dialup connection 
through a modem connected to the circuit pack. 
Finally, remember that IP trunk provides service between specific sites: the switch at 
each site must have the DEFINITY Internet Protocol Trunk (IP trunk) application or 
Lucent’s Internet Telephony Server-Enterprise (ITS-E) Release 1.2.
Administration overview
To administer IP trunks on DEFINITY ECS, you must complete the following tasks:
Planning Tasks
•
Plan routes and dialing permissions for IP calls by following the Procedures for 
Extension Dialing Between Sites, page 433, or by completing the Dial/Routing 
Plan Worksheets for remote off-premise dialing scenarios.
DEFINITY Tasks
•
Administer the IP Trunk circuit pack by completing the DS1 circuit pack screen 
(the IP Trunk emulates a T1 or E1 connection)
•Create a trunk group for the IP trunks and assign trunk group members to ports on 
the IP Trunk circuit pack
•Administer the AAR and ARS Digit Analysis Table using the information from 
the Switch Admin tables on the worksheets

Administration
NT Tasks
•
Log on to Windows NT and start the IP Trunk service
•Use the Configuration Manager to administer the routes and dialing permissions 
you defined on the Dial/Routing Plan worksheets or the procedures for extension 
dialing between sites.
•Use the Configuration Manager to set the IP Trunk service parameters
Plan call routing
Use the IP Trunk worksheets (shown at the end of this appendix) and/or the 
Procedures for Extension Dialing Between Sites to plan and coordinate your IP Trunk 
administration in Configuration Manager and DEFINITY ECS switch administration 
software.
You will create a dialing and routing plan, then use the information to administer 
DEFINITY ECS and the IP Trunk application. Read and follow these instructions 
carefully.
Using the Procedures 
for Extension Dialing 
Between SitesFollow these procedures for administering extension dialing between several sites. 
This section includes the steps for administration as well as examples using three sites 
that show DCS and non-DCS scenarios.
Using the Dial/Routing 
Plan WorksheetsThe worksheets are used for any two-site configuration allowing off-premise dialing. 
Worksheet 1 is used to capture general information about your site.
Worksheets 2–8 are used for different levels of off-premise dialing restrictions at the 
remote site, as listed in the following table. 
Off-Premise Dialing at Remote Site:
Worksheet 2: No off-premise dialing at remote site.

For any two-site configuration, you would fill out Worksheet 1 and one of the 
worksheets 2–8. Use the worksheets as follows:
1  Fill out the general information about your sites using Worksheet 1.
The Field Codes on Worksheet 1 consist of a number (1 or 2) that indicates the 
site, and a letter (A–J) that indicates a field on an administration screen. For each 
code, the Field Value column holds the specific value for that field for your 
switches. The field codes are used on all the other worksheets to indicate the 
values to enter from Worksheet 1. 
For example, field code 1A corresponds to the field International Access code for 
site 1. You would enter the value in the Field Value column for the International 
Access code for your site-1 switch. Then, when 1A appears on a subsequent 
worksheet, you would enter the value corresponding to 1A from Worksheet 1.
2  Use the second and subsequent worksheets to plan switch and IP Trunk 
administration. 
On each worksheet, in the Fill in with your actual values column, replace the 
indicated field codes with the corresponding values you entered on Worksheet 1.
For example, on Worksheet 2 there is a field called Different Country for each 
site. Its field code is 1A2B2D2E, which means that you would enter the values 
from Worksheet 1 as follows:

Once you’ve done this, the result is the exact phone number that you’ll enter in 
the matching field in the administration software.
Note:The IP Trunk application only recognizes digits. Don’t use characters 
such as ~w, ~p, + and so on in dialed digit formats that will be sent to IP 
trunks: the application won’t recognize these characters.
3  Use these worksheets to administer all your sites using IP Trunk. You can permit 
a different level of off-premise dialing for each site. For example, Site 1 may 
allow limited off-premise dialing, but Site 2 may not, and so on.
