Introduction to the T1 Interface Overview

Overview

Description of the T1

The T1 Interface is a digital trunk card that provides 24 voice channels over a four-wire circuit.

T1 lines can be leased from local exchange carriers and long-distance carriers.

Note: The current version of the T1 supports voice communications only. Data can be transmitted only if it reaches the T1 in analog form. Examples of analog data that can be transmitted over the T1 include fax transmissions or PC files that have been converted into analog form using a modem.

Framing Options

The T1 Interface takes an 8-bit sample from each of the 24 voice channels. These samples are grouped into 24 time slots, and each group of 24 slots is known as a T1 frame.

Since each of the 24 time slots contains 8 bits, the number of s ampling bi ts i n each frame equals 192 (24 x 8 = 192). In addition, a framing bit is added to the end of each frame to mark where the frame ends. The addition of the framing bit results in a 193-bit frame.

The T1 transmits these 193-bit frames at a rate of 8000 per second. The total number of frames (193) multiplied by the frame speed (8000 per second) results in a total transmission rate of 1.544 Mbps.

The T1 transmits the frames in groups of 12 or 24, depending on whether the SF or ESF framing format is used.

SF or ESF Framing Formats

The superframe (also known as SF or D4) format transmits the sampling frames in groups of 12. “Robbed bit signaling” is used to transmit signaling information for the frames. With robbed bit signaling, the eighth bit of each of the 24 samples is robbed from every sixth frame. The robbed bits transmit signaling states such as “onhook” and “offhook.”

The extended superframe (ESF) format also uses robbed bit signaling, but transmits the sampling frames in groups of 24. ESF supports monitoring and maintenance capabilities that are not available with the SF format.

Revised April 2000 DBS-2.3/9.2-500 1-3

Overview

Trunk Signaling Modes

The T1 provides the following trunk signaling modes. The signaling modes can be assigned on a per-channel basis.

• Loop start

• Ground start

•E&M

DNIS Service

The DBS T1 can be used for Dialed Number Information Service (DNIS). DNIS is normally used when multiple 1-800 lines terminate to the same

station or group. DNIS displays the last four digits of the dialed number, thereby allowing users to customize greetings for calls to different numbers.

Introduction to the T1 Interface

For example, an ACD group for ABC company may receive calls for sales and service. If the 1-800 number for sales is 1-800-555-4000 and the 1-800 number for service is 1-800-555-5000, the agents will know how to answer a ringing call by viewing their phone display. For instance, calls to the 4000 number may be answered “ABC Company--Sales Information,” while calls to the 5000 number may be answered “ABC Company--Customer Service.”

DNIS can be assigned on a per-channel basis.

Introduction to the T1 Interface Pre-Installation Requirements

Pre-Installation Requirements

Use the following guidelines to prepare your site for T1 installation.

Ordering T1

The following guidelines describe T1 options that must be ordered from your central office or interexchange carrier. 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, loop start, or ground start. For DNIS, order E&M with

wink start.

Trunk Signaling Wink start or immediate start/ringdown. Immediate start/ring-

down is used in most cases. However, if DNIS is used, order wink

start. Signaling Code DS-1 Line Code AMI or B8ZS. AMI is used in most cases. Framing Format D4 (Superframe) or ESF (Extended Superframe). D4 is used in

most cases. Signaling Method In-band Tones Order dial tone and ringback tone if provided by the CO.

Note: If the CO does not provide dial tone, program the DBS to

generate its own dial tone. See page 4-39. DNIS Service Order E&M trunk emulation with wink start signaling.

When the central of fice se nds a DID/DNIS ca ll to the DBS, it f irst

receives a wink from the DBS before sending the digits. Once the

wink is received, the central office should wait at least 200 ms

before sending the digits. Be sure to request the delay when order-

ing DNIS.

Note: The DBS supports four-digit DNIS service only.

Installation Guidelines

Guidelines

Read the following guidelines before beginning T1 installation. Installation instructions begin on page 2-14.

Hardware Requirements

• The system configuration determines what cards and cables must be purchased for T1. See “DBS Equipment” on page 1-6 for more information.

• The installer must provide a Channel Service Unit (CSU) that complies with FCC Part 15 and Part 68. The CSU is installed between the DBS and the public network. The CSU provides alarm, diagnostic, and monitoring functions, as well as network protection.

See “CSU Equipment” on page 1-7 for details on purchasing CSUs.

Maximums

• One T1 card can be installed per cabinet; the T1 card must be installed in the “EC/TRK” slot.

• The number of T1 cards that can be installed in two-cabinet systems depends on the sizes of the connected systems. Table 2-1 shows T1 maximums for two-cabinet systems.

Note: The DBS 72 + DBS 40 combination does not support T1.

Revised April 2000 DBS-2.3/9.2-500 2-3

Guidelines

Installation

• Fractional T1 can be used when fewer than 24 T1 trunks are needed. Fractional T1 allows you to use only a portion of the 24 channels provided on the T1 card.

• Though each T1 Interface provides 24 trunk channels, T1 trunks do not increase the overall trunk capacity of the DBS. Each T1 channel subtracts from the total number of analog trunks that can be installed. Furthermore, the number of analog trunks that can be used are always decremented in quantities of 8.

For instance, if you’re installing a T1 in a DBS 96 and you only want to use 12 T1 channels, the logical number of analog trunks that would be available is 20 (32 - 12 = 20).

However, because the number of analog trunks must be decremented in quantities of 8, the actual number of analog trunks that can be used is 16:

(32 total trunks - 16 (two 8-trunk increments) = 16.) Tables 2-2 through 2-4 show the possible combinations of analog and

digital trunks assignments based on system size. The trunk numbering shown in these tables is determined by backplane

trunk port assignments. Therefore, the numbering cannot be changed. Note: Analog trunks are numbered beginning with “1.” T1 trunk channels

are numbered beginning with the highest trunk channel used.

2-4 DBS-2.3/9.2-500 Revised April 2000

Installation Guidelines

Trunk Assignments for Single-Cabinet Systems

• Programming is not required to associate trunk ports with slot locations. However, you must use programming to specify that a combination of T1 and analog trunks is installed, and you must also specify how many T1 channels are used.

The following procedures provide step-by-step instructions for installing the CSU and the T1 Interface. The T1 procedure that you should use depends on the type of system you have and the number of T1s you are installing.

If you’re installing ... Use this procedure...

the Master and Slave” (page 2-21)

Installing the CSU

The following instructions explain how to install the CSU. See “CSU Equipment” on page 1-7 for specifications on CSUs and CSU cabling.

Note: The CSU should be powered locally, not through the CO line. Also, the CSU should be connected to an Uninterruptible Power Supply (UPS) to provide battery backup in case of AC power failures.

1. Connect the equipment cable from the DBS T1 MDF card to the equipment side of the CSU, as shown in Figure 2-1.

2. Connect the network cable from the network side of the CSU to the network demarcation point. (The network demarcation is typically an RJ48C “smartjack.”)

3. Test the CSU cabling by performing the following steps. Note: The following procedure can only be used with CSUs that provide a

local loopback. When testing the CSU, be sure it is set to “local loopback,” rather than “line loopback.” Line loopback provides a loopback between the CSU and the network.

The CSU can be tested only after the following parameters have been set. For a summary of these parameters, see Chapter 3, “Quick-Start Programming.” The page numbers included in the following table reference detailed descriptions included in Chapter 4.

a. Remove the jumper from CN4 on the Sync Card (Figure 2-3 on page 2-

15). b. Put the CSU in the local loopback mode. c. Check the CFA LED on the T1 card. If the LED is dark, the cabling

between the CSU and DBS is okay. If the LED is lit, go to the next step. d. Check the cabling from the DBS to the CSU. e. If you don’t find cabling errors, take the CSU out of local loopback

mode and reinstall the jumper on CN4 of the Sync Card. f. If the CFA LED remains lit, check the cabling from the CSU to the

network demarcation point.

chronizing the DBS with the public network. This parameter determines the first clocking source for network synchronization. If the first source fails, the system will switch to the second source. The system will attempt to go back to the first source based on the value entered under “Network Re-sync Timer” (page 4-7).

The system considers a clock source to have failed when the slip rate error counter is exceeded within a 24-hour period. (See page 430 for instructions on setting the slip rate error counter.)

In most cases, the 1st sync so urce is set to “1.” See page 3-5 for a list of typical sync source settings for single and double-cabinet systems.

will attempt to switch from the second source back to the first

source based on the valu e entered u nder “Networ k Re-sync T ime r”

(page 4-7).

If the second source fails and the first source is not working, the

system will switch to the third source.

In most cases, a system with one T1 has the 2nd sy nc source set to

“3.” Systems with two T1s normally have the 2nd sync source set

to “2.” See page 3-5 for a list of typical sync source settings for

single and double-cabinet systems.

One of the three sync sources should be set to “3” (free run). A

free-run setting is needed, so the DBS T1 can provide its own

clocking if the network clock fails.

(See “1st sync” for an introduction to clock synchronization.)

first source based on the value entered under “Network Re-sync

Timer” (page 4-7).

In most cases, a system with one T1 has the 3rd sync source set to

“0.” Systems with two T1s normally have the 3rd sync source set

to “3.” See page 3-5 for a list of typical sync source settings for

single and double-cabinet systems.

One of the three sync sources should be set to “3” (free run). A

free-run setting is needed, so the DBS T1 can provide its own

clocking if the network clock fails.

(See “Sync Source 1” on page 4-4 for an introduction to clock syn-

chronization.)

Notes:

more than one sync source.

Parameter Network Re-sync Timer Description If one clock source fails, the system will switch to another clock

source. The re-sync timer determines how often the system

attempts to return to the original clock source.

For example, if the first clock source (1st sync) fails, the system

switches to the second source. However, the system will try to

return to the first source based on the re-sync timer. Attempts to go

back to the first sync source drops all calls.

For instance, if the system changes to the second source at 12:00

p.m. and the re- sync time r is set for 24 hours, the DBS will att empt

to return to the first clock source at 12:00 p.m. every day. If the re-

sync timer is set for 1 hour, the DBS will attempt to return to the

first clock source every hour.

If the second source fails and the first source continues to be out-

of-service, the system switches to the third source. Again, the re-

sync timer determines ho w often the system will attem pt to return

to the first source.

Note:

When the system attempts to go back to the first clock

source, existing calls will be disconnected. Programming FF1 8# 4# 2# 1# (0-25)# Options 0-25

Parameter Digital Pad Settings Description Adjusts the volume of connections made via the T1. Default vol-

ume levels are included for connections between different types of terminals or circuits. For example, a K-TEL to T1 connection may use one volume settin g, while an SLT-to-T1 connection may use another.

The volume settings are controlled by changing a pad number, which in turn changes the loss or gain of the connection. In most cases, the default pad settings do not need to be changed.

Programming If the volume level of a connection is unsatisfactory, include the

receiving and sending circuit types in th e command, then ad just the volume by assigning a new pad number. Figure 4-1 shows the numbers used to identify each circuit type. Pad numbers are defined in Figure 4-3 on page 4-15.

Parameter Number of T1 Channels Description Determines how many T1 channels are used.

Though each T1 Interface provides 24 trunk channels, T1 trunks

do not increase the overall trunk capacity of the DBS. Each T1

channel subtracts from the total number of analog trunks that can

be installed. Furthermore, the number of analog trunks that can be

used are always decremented in quantities of 8.

For instance, if you’re installing a T1 in a DBS 96 and you only

want to use 12 T1 channels, the logical number of analog trunks

that would be available is 20 (32 - 12 = 20).

However, because the number of analog trunks must be decre-

mented in quantities of 8, the actual number of analog trunks that

can be used is 16:

(32 total trunks - 16 (two 8-trunk increments) = 16.)

Error Counters for FF Alarm Keys

The following counters determine when FF alarm keys light. FF alarm keys light when an error counter exceeds the specified number

within 24 hours. FF alarm keys can indicate the following types of alarms:

• Red alarms

• Loss of signal alarms

• Sync loss alarms

• Yellow alarms

• Slip alarms

• Frame loss alarms. In most cases, the default values for the error counters do not need to be

changed. The alarm keys can be assigned to any key telephone. However, the keys will

only work on a non-attendant phone that has the programming authorization code (#98 9999) activated. With attendant phones, the keys work whether or not the programming authorization code is activated.

For instructions on programming FF alarms keys, see page 4-42. Note: Once the alarm condition is corrected, the FF alarm key will remain lit

until the end of the 24-hour period, unless you enter the “historical error clearance” command. For a description of this command, see page 4-46.

Parameter Frame Loss Counter Description Determines how many fr ame los ses occur before a Frame Loss FF

Parameter DID/DNIS Description Determines if DID or DNIS is provided for a trunk. DNIS is avail-

able only with T1.

If DID is selected, the system uses a DID Numbers Table, which

allows the installer to assign up to 500 DID numbers. If DNIS is

selected, the syst em uses a DNIS Numbe rs Table, which allows the

installer to assign up to 500 DNIS numbers.

The DID Numbers Table can be used for DID or DNIS. Theref or e,

if all the numbers in the DNIS Numbers Table are used, a T1 chan-

nel can be set to DID, and DNIS service can still be used.

Notes:

1. The DBS only supports 4-digit DID/DNIS numbers.

2. When the central office sends a DID/DNIS call to the DBS, it

first receives a wink from the DBS before sending the digits. Once

the wink is received, the central office should wait at least 200 ms

before sending the digits. It is the installer’s responsibility to

Appendix A CPC-EX 1.0 Updates

CPC-EX Version 1.0 (and above) offers the following enhancements to the DBS phone system.

Note that every enhancement described here may not apply directly to T1. However, pay special attention to those that do as they may supercede information provided in the main chapters of this manual.

Compatibility

CPC-EX Version 1.0 supports all features of CPC-B Version 7.1 (with the exception of TSAPI support). In addition, CPC-EX Version 1.0 adds support for additional features, including the 44-Series phones, T1 Networking, and ISDN.

The CPC-EX card can be installed into an existing DBS cabinet, with no hardware modifications.

CPC-EX software uses existing CPC-B programming addresses, with the same numbering. Additional addresses have been added for CPC-EX features.

Note: CPC-EX requires SCC-B.

44-Series Phone Support

CPC-EX provides full support for Panasonic’s 44-Series phones (VB-44xxx). Table 1 below lists all 44-Series phone models and their part numbers. Most models are available in two colors: gray and black.

Appendix A. EX 1.0 Feature Update Section 400-Programming

Enhanced DBS features that can be executed on the 44-Series phones are described below:

Directory Mode

On the small-display phones, you can scroll through SSD names, PSD names, or extension names and select a displayed name for dialing.

Variable Mode

The small-display phones provide one-touch access to various features displayed during each of the following call states: 1) during an intercom call; 2) during CO dial tone; 3) during a trunk call; and 4) after dialing a busy extension.

Handset Mute

The large-display phone now contains a MUTE key, and a mute feature is available on all 44series phones. Pressing the MUTE key during an off-hook call will block audio from the handset transmitter to the outside party. You can still hear them, but they can’t hear you.

Off-Hook Monitoring

If you press the ON/OFF key during an off-hook call on any 44-series speakerphone, the other party’ s voice will be heard through both the handset and the speaker. This allows a third party to hear both sides of a conversation. Note: This feature does not activate your phone’s microphone - audio will be transmitted only through your handset.

Analog Adapter

The large-display phone can be enhanced with an analog port adapter which allows you to connect to an analog device such as a FAX or modem to the phone. This allows the same phone to be alternately used for analog or digital communications.

MSG (Message) Key

A MSG key on the large-display phone will perform Auto-Callback (automatically dialing the extension that sent a “Message Waiting” to your phone), or Auto-Answer Message (automatically dialing your voice mailbox).

DSS/72 and EM/24 - Key Arrangement

The keys on the consoles are arranged differently, affecting the text layout and default extension numbers assigned to these keys.

Section 400-Programming Appendix A. EX 1.0 Feature Update

FF-Key Programming

Because T1 Networking adds the capability of 4-digit extension numbering, you can now program up to 8 digits (not 6) into an FF-key.

Speed Dial Enhancements

CPC-EX supports up to 500 System Speed Dial (SSD) numbers. CPC-EX also allows SSD codes to be chained, or “linked”, to another SSD number, and either PSD or SSD codes to be chained to a PSD number.

Additional Serial Port

The CPC-EX card contains an on-board serial port (Serial Port 2) which can be used for Bus Monitor/Maintenance. This allows remote maintenance to be accomplished without disconnecting SMDR cabling.

T1 Networking Capability

Up to 4 DBS’s can now be connected together via T1 interface to form a DBS phone network. The DBS’s can be located in the same building, in separate buildings in a campustype environment, or at remote locations in separate states. Networked DBS’s use 4-digit extensions, with the first digit of the extension number identifying the DBS site.

Each site requires its own DBS cabinet with a CPC-EX card and a T1 card. Programming addresses are included in CPC-EX software for setting up the T1 Network. (see the T1

Networking Reference Manual for complete instructions.)

Modification to Toll Restriction Service

The program address for TRS Operator Access (FF7 1# 18#) has been modified to allow an extension to dial “0+NXX” phone numbers, even if “0-only” dialing is denied.

Maximum Time Priority Route Tables

CPC-EX allows a maximum of 8 Time Priority Route Tables (not 15) to be used during LCR programming. Since few systems use more than 3 Time Priority Route Tables, this change will allow the saved memory space to be used for future enhancements.

DBS-2.3/9.2-500 DBS Manual - Revised April 2000 Page A-3

Appendix A. EX 1.0 Feature Update Section 400-Programming

SMDR Modifications

SMDR reports contain several additional call types and other parameters due to CPC-EX support of T1 Networking and ISDN calls.

ISDN Support

CPC-EX supports ISDN-PRI (Integrated Services Digital Network -- Primary Rate Interface). The program address for Trunk Circuit Type (FF2 (trunk #)# 21#) has been modified to allow for ISDN. Programming addresses have also been added in CPC-EX to support ISDN. (See the ISDN Reference Manual for complete instructions.)

Modification to T1 Signaling Types

To allow easier programming of E&M trunks, CPC-EX uses “Wink Start” (not “Immediate Start”) as the default for T1 Incoming and Outgoing Signal Types.

Installation Notes

CPC-EX Installation

Use normal installation procedures to install the CPC-EX. The following illustration shows an installed CPC-EX:
