Introduction to DBS T1 Networking Overview
Overview
Description of T1 Networking
Two to four DBS systems may be interconnected using T1 connections to
create a DBS telephone network. The DBS systems may be located in the
same building, separate buildings, across the city or across the country.
DBS T1 Networking provides the following features:
• Network Extension to Extension Calling
• Call forwarding to Network Extensions
• Paging to Network DBS
• Network Route Selection
• Remote DBS CO Access
• SMDR Network Support
• Common Network Attendant Calling (calls that revert to the attendant will
go to the local attendant)
The T1 Network consists of two to four DBS systems that use 4-digit
numbering. The first digit (1 to 4) specifies the network DBS location (or
node) to receive the call. The remaining digits follow the conventional threedigit DBS numbering plan. For instance, dialing 2105 selects extension 105
on Network DBS node 2.

Introduction to DBS T1 Networking Pre-Installation Requirements
Pre-Installation Requirements
Use the following guidelines to prepare your site for T1 installation.
Ordering T1 Servi c es
The following guidelines describe T1options that must be ordered from your
central office or interexchange carrier (if used). These guidelines are designed
to cover almost all T1 installations. However, special requirements should be
discussed with your provider.
Table 1-1. Guidelines for ordering T1 services
Item to be Ordered Options
Line Type E&M with wink start for both incoming and outgoing calls.
Trunk Signaling Wink start
Signaling Code DS-1
Line Code AMI
Framing Format D4 (Superframe) or ESF (Extended Superframe). D4 is used in
most cases.
Signaling Method In-band
Tones Coordinate with T1 Service Provider.
Note: If the CO does not provide dial tone, program the DBS to
generate its own dial tone.
DBS-10-540 T1 Networking - Issued 9/6/96 Page 9
Pre-Installation Requirements
What You Must Purchase
Each DBS system in the network must have the appropriate T1 equipment as
described in the DBS T1 Reference Manual and the DBS Installation Manual.
Please refer to these manuals for a description of what must be purchased.
Note: The DBS T1 Trunk Card (VB-43561) must contain COP Version 2.0 or
later.
System Requirements
• A CPC-EX is required in every networked DBS system.
• Each DBS must contain one or two T1 interfaces with at least a portion of
the trunks dedicated to network traffic.
• Some DBS configurations limit the number of T1 interfaces that may be
used. See Section 500 - T1 Supplement for more information.
Introduction to DBS T1 Networking
Maximums
• Depending on the DBS cabinet configuration, each DBS in the network
may have up to 48 T1 trunks dedicated to T1 Networking.
Note: Any T1 trunks not dedicated to T1 networking may be used for
outside CO trunks. However each trunk used in the network diminishes the
number of T1 trunks available for outside CO connections. Trunk ports not
used by T1 (either with network or non-network) are available for CO
trunks.
• Up to four DBS systems may be included in the DBS Network.

Installation Instructions.
About the Example
Most forms in the following pages are followed by an example. For these
example forms, it is determined there are four locations across the country to
be networked together as follows:
• The sites are named after their locations -- Northwest (area code 202),
Northeast (area code 303), Southeast (area code 404) and Southwest (area
code 505)
• Each site contains dual-cabinet DBS 96 systems and contain two T1
interfaces
• The calling traffic between DBS systems is balanced (an even amount of
traffic is expected between systems). The maximum number of
simultaneous calls between any two DBS systems is expected to be 8 calls
or less.
• Every station is allowed to page anywhere on the network
• A network attendant is located at DBS 1
• Node Route Selection (routing calls to another node for outbound
processing) is to be used for calls in a remote DBS’ area code
• TRS is to be used to restrict long distance calls originating from a distant
DBS for some extensions.

Example
In this example call traffic is not expected to exceed 8 simultaneous calls.
Eight trunks for calls between any two DBS systems should be adequate.
However, under the T1 configuration being considered, a call can be relayed
by an intermediary DBS. In this case, a call will pass through one DBS to get
to another. Therefore a maximum of 16 network trunks between any two
systems should be enough. All remaining T1 trunks may be split off to handle
CO calls. Figure 2-5 illustrates the determined network trunk configuration.

The actual trunk numbers used and the Network Trunk Group Numbers must
be determined for each DBS. In this example, each DBS has two sets of
trunks for network calls. These paths are assigned a Network Trunk Group
number (either Network Trunk Group 1 or Network T runk Group 2) as shown
in Figure 2-6 below:

Network Trunk Group Selection
Each DBS system determines how to route a network call by selecting a
Network Trunk Group based upon the leading digit dialed. When a network
call is dialed, the system will try to route the call via an available trunk in the
Network Trunk Group with first priority. If no trunk in this Network Trunk
Group is available, the DBS will then try to route the call via a trunk in the
group with second priority then third priority. For each DBS, assign the
network trunk routing for each node number dialed using Table 2-9 through
Table 2-12:

Network Page Group Operation
DBS Networking allows paging across the network. An extension may
originate a page on a distant networked DBS by dialing the DBS node
number (1-4) followed by the Paging Access code. For example, to page DBS
node 3 Paging Group 01, dial 3#01.
A Network Paging Class of Service Parameter has been added to enable or
disable network paging. This Class of Service (COS) is then checked when a
network page is dialed to allow or deny the extension paging access.
The network DBS that receives a page request may also choose to allow or
deny a network page. A Class of Service may be assigned to each incoming
Network Trunk Group. If a page request is received on a Network Trunk
Group, its Class of Service is checked to determine if the page is to be
allowed or denied.
Assign network paging restrictions (enable or disable) to each Class of
Service.

In order for an extension to perform network paging, it must be assigned a
Class of Service that allows network paging.
Assign all extensions in the network an appropriate class of service to allow
or deny network paging. The receiving DBS may allow or deny network
pages by assigning a Class of Service to the incoming Network Trunk Group.

In order for an extension to perform network paging, it must be assigned a
Class of Service that allows network paging. In our example, we are
assigning all extensions to COS 1 that allows network paging.
The receiving DBS may allow or deny network pages by assigning a Class of
Service to the incoming Network Trunk Group. In our example, all network
trunk groups are assigned to COS 1 to allow network paging as shown in
Table 2-29 through Table 2-32 below.

Network Attendant Calling
DBS networking allows for calling a network attendant. This attendant may
be any DBS attendant in the network. If a user dials 0, the call is routed to this
system attendant.
Note: Calls that revert to the attendant will revert to the local attendant, not
the network attendant.

Node Route Selection (NRS)
Outside calls made on a DBS may be routed through another DBS before
outdialing to the public network. This is called Node Route Selection.
Typically, this is used to reduce long distance charges by routing calls based
on the area code(s) where the remote DBS is located.
Each DBS NRS table contains up to 50 NRS entries. Each entry contains the
dialed number to match (up to 6 digits), the minimum number of digits to be
dialed, and which network DBS (1-4) should receive the call. List any dialed
numbers to be included in NRS in Table 2-35 through Table 2-38.
If more than one NRS match is possible, then NRS will process the ca ll using
the NRS entry with the most complete match possible. For instance if one
DBS-2.3/9.2-540 T1 Networking - Revised April 2000 Page 29
System Planning Forms and Guidelines
NRS entry is 1201 and another is 12013, then if 12013333333 is dialed, then
the 12013 NRS entry is used. If 12014444444 is dialed, then the 1201 NRS
entry is used.
Note: If a call is routed to a remote DBS, LCR processing at the r emote DBS
may need to delete digits. For instance, if 1201XXXXXXX is routed by NRS
to a DBS in area code 201, the 1201 will need to be deleted by LCR when
dialed out by the remote DBS. (For information on LCR programming, see
the DBS Section 400 - Programming.)

Forwarding Incoming CO Calls to Another DBS Node
CO calls can be automatically forwarded to an extension or hunt group on
another DBS node based on Day, Night or Night2 mode.
The COs Day, Night and Night2 ringing assignments are set to have the CO
ring either immediately or delayed at ports 159-162 (virtual ports that have no
actual hardware present). Each of these virtual ports are then assigned to ring
at a network DBS extension number.

Chapter 3. Quick-Start Programming
The T1 Interface used with T1 Networking includes many programming
options, which allow you to customize how your T1 is used.
In most cases, however, you only need to set a few of the programs to get
your T1 Network online. This chapter summarizes the programs that are
essential to a T1 Network installation.
The following table shows the topics that are described in this chapter. For
detailed descriptions of all the T1 programs, see Chapter 4, “Programming.”

Before You Begin
Before you begin programming, you should be familiar with resetting the
DBS and performing the “New Function Reset” command. The following
paragraphs explain when these two procedures are used.
The New Function Reset command.
upgrading to a new DBS release, perform the “New Function Reset” before
you begin T1 programming.
You must perform the reset command if you’re upgrading to a completely
new release, but not if you’re upgrading to a point release. For example, if
you’re upgrading from Version 3.10 to Version 4.00, you need to perform the
reset. However, if you’re upgrading to a point release (4.06 to 4.07), you do
not need to perform the reset.
Manually Resetting the DBS.
reset to take effect. Program all of the quick-start items first, then reset the
system by powering it off then back on. (DO NOT RAM CLEAR!)
Hardware Setup
1. Install the T1 interface in each DBS using the Installation Procedures
described in Section 500 - T1 Reference Manual.
If you are installing T1 while you’re
Many of the T1 programs require a manual
Note: The DBS T1 Trunk Card (VB-43561) must contain COP Version
2.0 or later.
2. If no networked DBS has a T1 that connects to the public network, choose
one networked DBS as the clock source and strap its Sync Unit CN4
connector to Free Run. Strap all other DBS systems to Net. If an external
sync source clock is available, strap all DBS systems to Net.
For example, if two networked DBS systems are directly connected and no
other T1 is present, one of the systems must supply the sync clock and be
strapped for Free Run. However, if at least one of the systems has a T1
connection to the public network, this should be used to supply the sync
source clock.
Note: See “Sync Source Examples” on page 129 for more information.
3. For every direct connection between two networked DBS systems (i.e.
located in the same building), configure a direct connection cable as listed
in the following table.

Quick-Start Programming Programming Initial T1 Network Options
Programming Initial T1 Network Options
The following instructions explain the minimum programming required to
make the T1 Network operational. Default settings appear in bold.
Before attempting to program the network, fill out copies of the planning
forms supplied in Chapter 2 - System Planning.
The following procedures include several Recommended Check Points. It is
advised that the described checks be performed to test the network setup to
that point. Although it is possible to skip these checks, if these checks are not
performed it is difficult to isolate setup problems.
The following commands must be performed at each DBS in the network.
Also, many of the following commands require each DBS system to be reset
to take effect. After all quick start programming is completed (or as directed
at the Recommended Check Point) power the system off for at least 5 seconds
and then back on. It will take at least 1 minute for the T1 to synchronize after
the DBS systems are powered on.
Note: The T1 circuit card contains several status LEDs that may be checked
as the T1/T1 network is configured. The LED indicators on the front of the T1
card are as follows:
T1 LED INDICATION
CN3 After the T1 card has been initialized this light should begin blink-
ing. If this light does not blink the T1 card has not been properly initialized. Check the cabinet program settings.
CFA Carrier Failure Alarm. This LED lights when the DBS is unable to
synchronize to another T1 signal. The most common problem when
this LED illuminates is a RJ-41 wiring problem.
OOF Out of Frame. This LED will light when the DBS is unable to sync
to the T1 signal. The most common problem when this LED is illuminates is a wiring problem.
SLIP This alarm lights when the T1 senses a frame error. This LED tog-
gles off and on to indicate that slips have occurred. If the LED light
is on, this does not necessarily indicate that a slip has occurred.
YEL Yellow Alarm. If a Red Alarm occurs at the far end, the far end
sends a yellow alarm to the DBS. (A red alarm is when a loss of signal or out-of-frame conditions lasts for more than 2.5 seconds.)
AIS Alarm Indication Signal. This light is used for testing. It indicates
that all ones are being received.
LOOP Indicates the DBS T1 card is in loopback mode.

1. If you are installing the T1 while upgrading to a new DBS release, perform
the “New Function Reset” command.
Note: You must perform the reset command if you’re upgrading to a
completely new release, but not if you’re upgrading to a point release. For
example, if you’re upgrading from Version 3.10 to Version 4.00, you need
to perform the reset. However, if you’re upgrading to a point release (4.06
to 4.07), you do not need to perform the reset.

Parameter Extension Number Digits
Description (4-digit number added to support network operation)
Determines whether the DBS will use 2-digit, 3 digit, or 4digit extension numbers.
If 2-digit numbers are used, a maximum of 60 numbers are
available for assignment. Number Range: 10 through 69.
If 3-digit numbers are used (default setting), a maximum of
600 extensions numbers are available. Number Range: 100-
699.
If 4-digit numbers are used, the DBS must be configured as
part of a DBS network. A maximum of 600 extension
numbers are available on this DBS. The first digit is
determined by the network node number for the DBS (1, 2, 3,

Note An incoming call detection and processing time must be
added to determine the actual ti me before a wink signal is
sent back. Typically this time is from 110-120 ms. For
instance, if the Wink Signal Delay Answer T imer is set to
100 ms, the actual wink will occur after approx. 210 ms.

caller from being able to access a trunk and dialing “0”,
“00”, “10XXX0”, or “101XXXX0” to reach an operator.
This prevents a user from being able to make a restricted
phone call by asking the operator to place the call for him
“101XXXX0”-only calls, but allow “0+NXX” calls if
permitted by TRS tables
1=Allow “0/00-only”, “10XXX0-only”, and “101XXXX0-
only” calls, and also allow “0+NXX” calls if permitted by
TRS tables
2=Deny “0/00-only”, “10XXX0-only”, and “101XXXX0-
only” calls, but allow “0+NXX” calls regardless of TRS
tables
3=Allow “0/00-only”, “10XXX0-only”, and “101XXXX0-
only” calls,and also allow “0+NXX” calls regardless of
TRS tables
Note The Operator Access address still applies only to DBS sys-
tems using the new (1995) NANP dialing plan (FF7 1# 17#
1#), and to TRS types 2-6 (TRS types 0 and 1 do not allow
outbound dialing; TRS type 7 allows all dialing).
If “0/00-only” calls are denied (settings 0 or 2), the system
will wait 6 seconds before automatically disconnecting the
call. However, if the user dials additional digits within 6
seconds, the DBS will check other TRS switches to deter-
mine whether to allow or deny the call.
For all settings (0 -3), th e sy stem will che ck the CIC F or mat
switch (FF7 1# 21#...) if an interchange carrier code is
dialed.
For all settings (0-3), the syste m will check the inter national
calls switches (FF7 1# 1# and FF7 1# 19#) if “01” or “011”
is dialed.
For settings 0 and 1, the system will additionally check TRS
tables for the TRS type assigned to the trunk and the FF7
settings for that TRS type (such as allowed/denied area
codes, office codes, and 7-digit dialing).

Parameter Overseas Call
Description Use this address to allow or deny international calling on
incoming network trunk group calls as follows:
• When a network caller attempts an overseas call
(trunk access + 01 or 011) on a trunk assigned TRS
type 3-6, the system checks the setting in this
address (default=deny call).
• However, if this address is set to “1”, the system
checks the “International Calling For TRS Types 36” (FF7 1# 1#) to see if the dialed country code
should be checked against the Country Code Table
(FF7 1# 20#) before allowing the call. If so, and if
the dialed country code is included in the table, the
call is allowed.
