2.3.7Connecting DSS consoles to Avanti telephone sets
You can connect up to four DSS units to each Avanti telephone set.
When making the connections, refer to Figure 2-6, below.
1.Lay the telephone set and the DSS console face down.
2.The stands of both the set and the console extend upward from 
the back of the telephone set. Pull down on the each stand to 
snap it out of place.
3.Remove the plastic piece covering the RJ45 socket A in the back 
of the telephone set.
4.Insert the RJ45 connector on one end of the cable to the RJ45 
socket A in the back of the telephone set. 
NOTE 
If the telephone set has a option module 
connected to it, the cable is connected to the 
option module, instead of the telephone set 
(see Section 2.3.5).
5.Fit the cable into the horizontal cable slot on the left side of the 
telephone set. 
6.Insert the RJ45 connector on the other end of the cable to the 
RJ45 socket B on the right side of the DSS console. (First 
remove the rubber plug covering the socket).
7.Use the DSS console bracket to connect the DSS console and 
the telephone set. The right side of the bracket (with four holes) is 
attached to the telephone. The left side of the bracket C (the side 
with two holes) is attached to the DSS console.
8.Insert two screws in the inner holes D on the right side of the  Table 2-4:  PC wiring connections

9.Insert two screws in the holes F on the left side of the bracket and 
connect the bracket to the DSS console.
10.If you are connecting only one DSS console, snap the stands of 
the telephone set and the DSS console back into place. 
To connect an additional DSS console
When making the connections, refer to Figure 2-6, below.
1.Lay the telephone set with DSS console and the additional DSS 
console face down.
2.Remove the stands from the DSS consoles by snapping them out 
of place.
3.Remove the rubber plugs covering the RJ45 sockets G on the left 
side of the installed DSS console and the right side of the addi-
tional DSS console.
4.Insert the RJ45 connector on one end of the short cable H to the 
RJ45 socket on the left side of the DSS console connected to the 
telephone.
5.Insert the RJ45 connector on the other end of the short cable H to 
the RJ45 socket on the right side of the additional DSS console.
6.Fold the cable over so that the DSS consoles fit closely together.
7.Use the DSS bracket to connect the DSS consoles.
Insert two screws in the outer holes E on the right side of the 
bracket C and fasten them to the installed DSS console.
Insert two screws in the holes F on the left side of the bracket C 
and fasten them to the additional DSS console.
8.Repeat for any additional (for a total of up to four per telephone) 
DSS consoles that you want to connect to the telephone set.
9.Snap the stands of the telephone set and the DSS consoles back 
into place.

The Voice Recognition card is installed in the same way as the data 
cards (see Section 2.3.3). 2.5DIGITAL PRIVATE NETWORK
In SB7/DB7 there are two types of PRI card groups:
•Cards used for connection to the CO
P30 and P24 cards using ETSI, DMS100, AT&T 4ESS or AT&T 
5ESS protocols, and
•Network cards
N10/20/30 (2M) and N12/24 (1.5M) cards using DPNSS or QSIG 
protocols.
SB7/DB7 supports both DPNSS (Digital Private Network Signaling 
System) and QSIG digital protocols for a private network in sys-
tems with either T1 or E1 lines.
SB7/DB7 continues to support NAP (Network Analog Protocol) for 
networking small SBS systems on E1/T1 cards. 
						

							76-110-0175/G, Issue 2
2-12DPNSS protocol
DPNSS is a BT protocol and recommended for use wherever possi-
ble, particularly when one or more SBS is connected in a back-to-
back network. It is required in the UK and optional in some other 
countries (Israel, USA, South Africa, Germany). In every country it 
supports all system features regularly supported by analog lines, 
and, in a back-to-back network, it supports all new system features.
QSIG protocol
The QSIG protocol is a standard protocol that defines signaling re-
quirements at the Q point. SBS supports only basic call features. At 
present time it is the only way, or the preferred way, to network sys-
tems in some countries.
Installing network cards
The new network cards are installed as PRI cards with the following 
exception:
Using DPNSS protocol in the UK
The N10, N20, or N30 network card may be installed in the UK for 
using DPNSS protocol in one of two ways:
•standard installation for a twisted pair connected to the RJ45 
connector, as for a PRI card
•using an adapter between the card’s RJ45 connector and a coax-
ial cable connecting it to the network. 
Use an adaptor, such as the Black Box Corporation’s MT242A-F 
adaptor. Simply use regular eight wire cable to connect the adap-
tor’s balance connector to the network card’s RJ45 connector 
and plug the coaxial cable into the adaptor’s transmit and receive 
sockets.

							Section 2: INSTALLATION
2-13 NOTE 
Because SB7/DB7 does not support the provi-
sions of the Generic functional protocol for the 
support of supplementary services, it should not 
be installed as a transit system between PBXes 
that support services based on the Generic func-
tional protocol.2.6MPD CARD - DIGITAL 400 SYSTEM
DIGITAL 400 Release DB7 has a new MPD card. Cabinet placement 
is the same as for the earlier versions of the MPD card. 
There are changes in the LEDs and external connections on the 
MPD cards as shown in Figures 2-8, 2-9, and 2-10.

ADMINISTRATION3.1GENERAL
The administration of Release 7 of the DIGITAL systems is the same 
as that of Release 6, except for those features described in this ad-
dendum.
The programming changes described below are summarized in 
Appendix A.
Refer to the Release 6 Administration manual.
NOTE
•On the MPD card in the DIGITAL KEY BX sys-
tem, the lower RJ45 connector is used for con-
nection to the computer used for programming
or loading the system configuration file (see
Figure 3-1).
•The default baud rate for the MAP port on
DIGITAL KEY BX, DIGITAL 400, and DIGITAL
1000 systems is 38,400 baud.

3-23.2AVANTI FAMILY OF TELEPHONE SETS PROGRAMMING
Avanti telephone sets are supported by the ULD and UHD cards. 
Each ULD card provides ports for up to 16 Avanti telephone sets. 
Each UHD card provides ports for up to eight Avanti telephone sets. 
Each one of these telephone sets may also support a data card.
3.2.1CARD CONFIGURATION Screen [YC-SC]
Legal values for the card following cards have been added: ULD and 
UHD (for Avanti telephones) and N24, and N30 (for QSIG and 
DPNSS network cards). Define these cards and enter their CARD 
DEFINITION Screen as you do for any other card.
3.2.2ULD CARD DEFINITION Screen [YC-SC-F9]
Figure 3-2 shows the ULD CARD DEFINITION Screen, 
Figure 3-2  ULD/UHD CARD DEFINITION Screen
This card supports up to 16 Avanti telephone sets and their add-on 
units. The values for entering the station type in this screen appear 
in bold. The telephone sets may be of the following types:
•Avanti 3025 - Graphic display (Full duplex) E30
•Avanti 3020F - Four line display (Full duplex) D30
•Avanti 3020H - Four line display (Half duplex) D30
•Avanti 3015DF - Two line display (Full duplex) S30
•Avanti 3015DH - Two line display (Half duplex) S30
•Avanti 3015H - No display, 15 buttons (Half duplex) B30
•Avanti 3000 - No display, four buttons (Half duplex) M30
•Avanti Attendant - Graphic display ATT.  
						

							Section 3: ADMINISTRATION
3-3 For each station assign a DN, the type of station (see below), desig-
nate whether it is single or dual audio path, and its add-on unit, if any. 
The add-on units may be defined as the following types:
•DSS1- DSS8 - direct station select console
•VRC - voice recognition card
•TAPI - Avanti DATALync data card
•PCAPP - Avanti APPLync card in PC application mode.
When using a data card, it must be defined as the first add-on for its 
station.
3.2.3ATTENDANT DEFINITION Screen [AT-AD]
The fields ST20 ATT MAP and ST30 ATT MAP have been added to 
the ATTENDANT DEFINITION Screen to designate the attendant 
maps that apply to the DIGITAL model Attendant Consoles or to the 
Avanti model Attendant Consoles.
The field ST20 ATT MAP is for programming the appropriate softkey 
key map for Attendant Consoles belonging to the DIGITAL family of 
telephone sets.
The field ST30 ATT MAP is for programming the appropriate softkey 
key map for Attendant Consoles belonging to the Avanti family of 
telephone sets.
In both the ST20 ATT MAP and ST30 ATT MAP fields, the legal 
values are: 1-4 for DIGITAL KEY BX and DIGITAL 400 systems and 
1-24 for DIGITAL 1000 systems.
NOTE
The same logical attendant position can simulta-
neously support a mix of some DIGITAL model
Attendant consoles having the ST20 ATT MAP
and some Attendant consoles of the Avanti model
having the ST30 ATT MAP.
