Features
Features
The T-Comfort 930 DSL is a communications system for integrated voice and data communication. The out-
standing feature of this communications system is its modular structure:
■ Even with the smallest T-Comfort 930 DSL version, it is possible to use all the most important communi-
cations applications. The basic module enables telephony with system telephones, ISDN telephones and
analogue terminals, Internet / intranet data communication, CTI applications, sub-system operation and
system configuration using a standard Web browser.
The expansion module of the T-Comfort 930 DSL provides three slots for further interface cards. Using
different combinations of interface cards, the configuration of the T-Comfort 930 DSL can be tailored ex-
actly to your communications requirements. The need for additional U
S
ports or more a/b ports can be met using one or more interface cards without changing the system.

intercom and a serial interface. For a T-Comfort 930 DSL version 2 we recommend to connect a Doorline
entrance intercom (see Intercom System (for a/b) starting on page 42).
■ You can use an additional insertable memory card (CompactFlash) to operate further program packages.
■ Another special interface card provides an internal U-R2 compatible T-DSL modem. Additional infor-
mation can be found in the corresponding user manual of the DSL modem.
Cascading
Using the expansion module, the T-Comfort 930 DSL can be cascaded with a second T-Comfort 930 DSL
communications system.
Tel ep ho ny
The T-Comfort 930 DSL communications system is designed to be connected to an ISDN basic access using
the DSS1 protocol. System access (point-to-point) and multi-terminal access (point-to-multipoint) are both
supported. The two forms of access can be configured in parallel.
For this purpose

Features
■ the T-Comfort 930 DSL expansion module with additional interface cards provides up to eight further S
ports (switchable between internal/external). An overview of the available cards can be found under
Interface Cards starting on page 31,
The firmware of the T-Comfort 930 DSL is designed for configuring up to 300 users.
You can connect the following devices to the T-Comfort 930 DSL:
■ analogue terminals
■ Euro-ISDN terminals
■ T-Comfort 630, T-Comfort 730 and T-Comfort 830 system telephones
■ Comfort Pro P 100, Comfort Pro P 300 and Comfort Pro P 500 system telephones
■ T-Comfort 730 DECT base stations

the T-Comfort 630/730/830 Comfort Pro P100/300/500 system telephones. T-Comfort 730 DECT base sta-
tions can also be connected to the DECT-enabled U
ports on interface cards. An analogue port is used by
pn
standard analogue devices.
If the CNIP (calling name identification presentation) feature is supported by your network provider, the latter
will show you the name of callers in addition to their number for each incoming trunk call. The T-Comfort
930 DSL supports the display of the name on system telephones. However, if you have created an entry in the
telephone book of the T-Comfort 930 DSL under the number of the caller, this will be displayed instead.
The T-Comfort 930 DSL can be integrated into an existing network (LAN) and be used by all workstations as
an Internet access router and mail client.
Configuration and programming of the T-Comfort 930 DSL is performed by means of a special Web browser
(known as the “Web console”), which can be run on a connected PC.
The T-Comfort 930 DSL can be configured and maintained from the T-Com service centre via remote access.
A PC can be connected via a retrofitted V.24 module (only possible on the T-Comfort 930 DSL version 1) to
the COM port for the purpose of configuring the system or transferring connection data.
10
Features
To connect the T-Comfort 930 DSL to existing company hardware, two “actor” ports (output) and three
“sensor” ports (input) can be provided by retrofitting a doorstation module (only possible on the
T-Comfort 930 DSL version 1). For example, this can be used to operate a door opener and a doorbell via the
T-Comfort 930 DSL (this requires additional equipment).
The T-Comfort 930 DSL allows you to use CTI (Computer Telephony Integration) applications made by other
manufacturers. This requires installation of a TAPI driver on a Windows PC (see Setting up TAPI starting on
page 111). The T-Comfort 930 DSL also has an integrated dialling wizard: the Telefonie-Assistent. Via the
Telefonie-Assistent users can call up and use telephone functions on PCs without first having to install a
special TAPI driver.
The T-Comfort 930 DSL complies with the regulations for telecommunications equipment. The DSS1 pro-
tocol is implemented.
Packet data in the D channel
Some business applications, for instance POS terminals, cash registers or credit card terminals, require a per-
manent data connection over the X.25 packet data network. Packet data transfer through the ISDN D channel
(according to X.31 via SAPI 16) can also be established between several S
interfaces of the T-Comfort
0
930 DSL. Simultaneous connections are distinguished by means of a TEI (Terminal Endpoint Identifier).
X.31 packet data can be forwarded between two S
interfaces (for instance an internal and external S0
0
interface). Equally, data can be forwarded (“routed”) over permanent Q.SIG lines. It is possible to operate mul-
tiple terminals with the same TEI on different internal S
connections to be routed to the same external S
0
interfaces. A TEI mapping table allows these X.31
0
interface.
The routing table for X.31 packet data is set in the Configurator under PBX Configuration: X.31. Additional
information can be found in the Configurator online help files.
Internet Access
It is possible to connect individual PCs to the T-Comfort 930 DSL via the internal S
ports, or to connect an
0
entire LAN to the T-Comfort 930 DSL via the Ethernet port. These PCs can access the Internet via the
T-Comfort 930 DSL. If Internet access is already available from an Internet service provider, this can be con-
figured in the T-Comfort 930 DSL. If the client network is not IP-capable, the T-Comfort 930 DSL can admin-
ister the IP configuration necessary for Internet access. The T-Comfort 930 DSL has an integrated DHCP
server and a DNS server, which in this case take over IP address administration and name resolution for the
client PCs.
11
Features
The T-Comfort 930 DSL enables Internet access for all connected PCs by means of a common IP address.
Only this is externally visible. The local IP addresses of the client PCs are translated to the IP address of the
T-Comfort 930 DSL by network address translation (NAT). In this way the client PCs in the LAN cannot be
reached directly from the Internet. This protects them from direct external attack. The LAN is additionally pro-
tected by the T-Comfort 930 DSL filter lists, which can be customised individually (firewall function).

Note: We recommend you to read through the explanations under Useful Information
on Internet Access starting on page 74.
DECT Data Communication
The T-Sinus 61data, T-Sinus 620data or the T-Comfort 830 handset enable PCs that are not connected to the
T-Comfort 930 DSL via the internal S
make full use of all the Internet and e-mail features of the T-Comfort 930 DSL.
Data is transmitted via the internal data interface of the T-Comfort 830 handset. For this the handset is con-
nected via a supplied adapter with the serial port of the PC. The Internet can then be accessed directly via the
remote data transfer (i.e. dial-up) network. The T-Comfort 830 handset sets up a data connection with the
T-Comfort 930 DSL via the DECT air interface. The remainder of the connection set-up is either direct -
through an ISDN B-channel - or indirect - through the internal RAS access of the T-Comfort 930 DSL. Indirect
RAS access is preferable. This uses the routing function of the T-Comfort 930 DSL and thus also the security
features of the shared Internet access.
Using the T-Sinus 61data/T-Sinus 620data a PC can set up an ISDN data connection via DECT. The
T-Sinus 61data/T-Sinus 620data is connected to the PC via the USB interface.

For detailed information on the installation of the required driver software and the various types of configu-
ration, refer to the chapter T-Sinus 61data/T-Sinus 620 data on the T-Comfort 930 DSL starting on
page 119 and the user guide for the T-Comfort 830 handset. For information on configuration of the
T-Comfort 830 handset with a data interface, please refer to the online help documentation of the
T-Comfort 930 DSL.
E-mail
The T-Comfort 930 DSL has an integrated e-mail function that is able to use the POP3, APOP or IMAP4 pro-
tocols to check the Internet service provider for incoming mail. When configuring the T-Comfort 930 DSL, e-
mail account query can be configured for every member of staff. The T-Comfort 930 DSL then fetches the
incoming e-mail headers (subjects) and senders from the mail server at set intervals, and forwards them to
users’ system terminal.
12
Features
E-mail accounts for the sending e-mail can also can be configured for users. E-mails can then, for example, be
sent directly from the Telefonie-Assistent to other users. In addition, users who have had a voicebox con-
figured for themselves, can let themselves be notified of new voicebox messages via e-mail.
Important events and errors are kept by the T-Comfort 930 DSL in an internal log book: the error store. To
inform or alert the system administrators, entries in the log book (system messages) can be sent via e-mail.
Further Network Features
You can offer staff the possibility of dialling into the LAN by means of RAS access.
A LAN-to-LAN link can also be implemented by ISDN. In this way two T-Comfort 930 DSLs can connect their
LANs by dial-in on demand.
A NET-CAPI program (driver software on the system CD-ROM) allows you to use ISDN functions on those PCs
that do not possess a built-in ISDN card.
Further Telephony Features
Installing an extra memory card allows you to operate a digital voice memory and voice information system.
For more information, refer to the user guides called “Comfort Pro A IAB (integrated answering machine)”
and “Comfort Pro A IAM (interactive call manager)”.
You can optimise your telephone communication by using the team functions and the call-queuing function.
With an additional licence, the web application “Comfort Pro A IVE (integrated connection data recording)”
can be used. This web application enables you to register and store telephony connections and evaluate the
connections with user defined filters. Further information can be found in the online help of the web console.
You can connect two T-Comfort 930 DSL communications system with each other (cascading). Using PBX
cascading you can increase the number of connectible devices in a simple way.
As your company’s requirements grow, the T-Comfort 930 DSL can be networked with other telecom
systems. The T-Comfort 930 DSL can then operate as a sub-system or DECT server. To operate the system as
a DECT server the system’s U
ports must be DECT-capable. It is also possible to create a telecom system
pn
with several networked telecom installations.

minal functions of the T-Comfort 930 DSL. The “Standard” user group, because of its default settings, is well
suited as a starting point for the creation of user groups for normal users of the system (e.g. the staff members
of a company).
N
Note: When the T-Comfort 930 DSL is commissioned, all connected terminals are ini-
tially in the “Administrators” group until a user logs on to the Web console. Subse-
quently, all terminals are automatically in the “Guests” group (see also the chapter
entitled Configuring the T-Comfort 930 DSL starting on page 56). For more details on
the configuration of user groups, refer to the online help in the chapter entitled “User

Installation Installing an Expansion Set
To fasten the screws at points B and C, remove the cover of the T-Comfort 930 DSL and insert the screws in
the holes provided for this purpose. The T-Comfort 930 DSL is suspended from the screw at point A, so there
must be a space of 3 mm between the screw and the wall.
Installing an Expansion Set
You can either install the expansion module when you first assemble the system or later as part of a system
upgrade. In both cases, follow the mounting sequence as described here:
1. Turn off the T-Comfort 930 DSL. Unplug the plug-in power supply from the socket. You should not install
the expansion module or install or uninstall additional interface cards while the T-Comfort 930 DSL is
turned on.
2. Open the housing cover of the T-Comfort 930 DSL. In this case, carefully follow the Safety Precautions
starting on page 19.
The existing basic module is mounted in the left half of the housing. No components may be mounted in
the right half of the housing.
3. Place the expansion module in the intended mounting location in the right half of the housing. Be sure to
align the 96-pin connector properly to the socket on the basic module. Push the expansion module

page. The Status column in the table displays a green tick beside the name of the interface card.
Slots for Additional Interface Cards
The T-Comfort 930 DSL has three large slots in which you can operate interface cards. Each interface card is
connected to via two port jacks. The following properties characterise the large slots:
■ There is no prescribed order in which to use the jacks. You can, for example, therefore operate an
interface card in slot 3 even though slot 2 is not occupied.
■ Each of the slots is connected to a group of pressure terminals. Therefore there are also three pressure
terminal groups on the expansion module. To be able to distinguish these, all the pressure terminals in a
group are the same colour.
■ The slots are not of the same type. Therefore some of the available interface cards may not be operated in
all slots. Note the overview under Interface Cards starting on page 31.

Port Assignment, Termination, Cable Lengths Installation
Doorstation equipment can be activated on an a/b1 port of a T-Comfort 930 DSL Version 1. In this case, an
electronic switch enables the low-frequency voltage to be separated from the feed.
Actor/Sensor
N
In order to operate an entrance intercom and door opener (only T-Comfort 930 DSL Version 1), you need four
twin-wire cables:
■ one cable between the entrance intercom and the a/b1 port,
■ one cable between the door opener and the Actor1 port,
■ one cable between the intercom input and the Actor2 port to activate the amplifier as well as
■ one cable between the doorbell and the sensor port.
Only use entrance intercoms and door openers complying with the German FTZ Guideline no. 123D12.
LAN Port
Note: With the T-Comfort 930 DSL Version 2 a door station of the type “DoorLine” can
be operated (see Intercom System (for a/b) starting on page 42).
The LAN port on the basic module enables integration of the T-Comfort 930 DSL into an existing in-house
LAN by means of a 10 Mbit hub.
The LAN ports on the expansion module (LAN0, LAN1 and LAN2) lead to the Ethernet switch of the
expansion module. These LAN ports support 10 Mbit/s and 100 Mbit/s transmission speeds in half- or full-
duplex operation. The change in transmission rate and mode of operation is automatic (“auto-sensing
function”). The switch is also automatic for connections which require a crossed LAN line. For this reason, you
can also use an uncrossed LAN line for a connection to another hub or switch.
A LAN line (twisted-pair line in accordance with 10BaseT or 100BaseTX) can be up to 100 m long. Secure
operation with 100 Mbit/s requires the use of category 5 lines and line sockets. Use a shielded Ethernet cable
(STP cable, Shielded Twisted Pair cable).

T-DSL Port
With the T-Comfort 930 DSL, an external T-DSL modem as well as an internal T-DSL modem (realized as a
special interface card) can be operated. Further explanations regarding the integrated U-R2 compatible DSL
modem can be found in the “DSL Modem for T-Comfort 930 DSL” manual.
External T-DSL modems can be connected via the LAN port. In the case of the T-Comfort 930 DSL, the output
of the T-DSL modem (NTBBA) is led to the LAN port of the T-Comfort 930 DSL via an external switch or hub.
The router subsequently converts the T-DSL protocol to the TCP/IP protocol of the LAN.

cross-wired line with a LAN port of the expansion module. If you are operating the
T-Comfort 930 DSL as a slave system in a cascaded PBX, the LAN0 port on the expan-
sion module of the slave system can be used instead (see PBX Cascading starting on
page 77).

Power Failure Installation
Power Failure
In the event of a power failure, all the contents in the memory (program and user data) are saved without
change. The internal clock continues to run for 24 hours. If the power failure lasts longer than 24 hours, the
time and date are reset to the factory setting when power is switched on again. When the first external out-
going call is made, the time and date are set to the current value as given by the exchange. With the
T-Comfort 930 DSL Version 2, date and time generally will be adjusted after the first outgoing connection.

COM Port
By installing theV.24 module (only for T-Comfort 930 DSL Version 1) a serial port on the COM interface is pro-
vided.
S
A PC for configuring the T-Comfort 930 DSL or transmitting call data can be connected to the COM port. This
call data can be evaluated in detail with a call charge registration program (e.g. DGV at T-Comfort).
LAN Port
Using the LAN port (Ethernet) you can integrate an T-Comfort 930 DSL into your corporate network (local
area network), and thus use it, among other things, as an IP router for accessing the Internet.
The LAN ports of the Ethernet switches on the expansion module process Ethernet data traffic with different
degrees of priority. You should therefore assign the three LAN ports on the expansion module as follows:
■ LAN2: Use this port if you cascade a second communications system as a slave system (see PBX Cas-
cading starting on page 77).
■ LAN1: Here connect the short Ethernet connection line to the basic module.
Please note: The connection line for the COM port can be up to three metres long.
■ LAN0: You should use the port with the lowest priority to connect to your corporate network.
Both internal LAN ports of the Ethernet switch are reserved for usage on interface cards.

Configuration
Configuration
Configuration and programming of the T-Comfort 930 DSL is performed by the Configurator, a special
software application integrated into the system. The Configurator is operated via the Web console, which can
be run on any PC connected to the T-Comfort 930 DSL.
The T-Comfort 930 DSL Web console
Using the Web console, you can:
■ perform the initial configuration of the T-Comfort 930 DSL,
■ configure users of the T-Comfort 930 DSL and authorise them to use certain system services,
■ carry out further system maintenance,
■ use PC-supported telephony functions,
■ read out call charge information,
■ access the T-Comfort 930 DSL telephone book.
The Web console has an integrated online help function that offers comprehensive information on configu-
ration and maintenance of the T-Comfort 930 DSL (see Loading the Online Help starting on page 59).
For the initial configuration you can connect the PC to the T-Comfort 930 DSL via the Ethernet port. A COM
port can also be used. The TCP/IP network protocol is used to set up a connection via one of these ports. You
can then open the Web console of the T-Comfort 930 DSL and call up the Configurator from there.

Receiving System Messages as E-Mail
Important events and errors are kept by the T-Comfort 930 DSL in an internal log book: the error store. To
inform or alert the system administrators, entries in the log book (system messages) can be sent via e-mail.
In order not to notified of every error, the administrator can define corresponding log filters (in the Configu-
rator, the LOG Configuration: LOG Filter menu). These filters define which errors (category, severity, number
per time interval) should be notified. The e-mails always include an internal event or error number, as well as
an explanation of the message. Further, extra parameters (such as the port number when a trunk line drops
out) are also provided.
The mail account for this service (Account for LOG filter) is configured in the Configurator,

Generating Your Own MoH Files
The T-Comfort 930 DSL comes with an internal MoH file for Music on Hold. The T-Comfort 930 DSL product
CD contains a number of MoH files with different volume levels, which you can load at a later time as nec-
essary.
The file format for non-resident Music on Hold is *.wav. You can also save your own MoH in a *.wav file and
load it into the T-Comfort 930 DSL.
If you have a Windows operating system, you can use the “Sound Recorder” program to generate your own
MoH file. This program is usually located in the Windows directory called “Multimedia”.
The MoH file must be coded with 8000 Hz, 8 bit mono in accordance with CCITT, A-Law. This coding is
required for the T-Comfort 930 DSL and can be set in the “Sound Recorder” when you save the file under
Format (CCITT, A-Law) and Attributes (8000 Hz, 8 bit mono). The maximum allowable size for a MoH file is
63
Configuration Configuring the T-Comfort 930 DSL
256 KB (approx. 32 sec. play time). If a larger file is loaded then this will be “truncated” and thereby will also
only be played for 32 seconds. The MoH capacity can be subdivided in a maximum of 5 files. These files can
be used for different companies or for internal and external calls.
N
Load your MoH file in the Web console's Configurator, in the SYS Configuration: Components menu.
N
Note: If you don't have the Sound Recorder program or the appropriate codec on your
Windows operating system, you should install these components from your Windows
CD.
Note: When generating your own MoH file, you may incur a fee for the use of non-resi-
dent melodies (e.g. a GEMA fee in Germany or MCPS fee in the UK). The MoH files that
come with your T-Comfort 930 DSL can be used free of charge.

T-Comfort 930 DSL in Computer Networks
One of the outstanding features of the T-Comfort 930 DSL is the integration of telephony and computer net-
works. Connect the T-Comfort 930 DSL via a computer network (LAN) with suitably configured workstations,
and you can use its network features from these workstations. Using a Web browser you can access:
■ the T-Comfort 930 DSL Configurator
■ call charge administration
■ the Telefonie-Assistent, with which telephone functions can be used on a PC
■ the T-Comfort 930 DSL central telephone book and your personal telephone book as well as to the
company telephone book (if the multi-company variant is activated).
In addition, the T-Comfort 930 DSL can be used as an Internet access server. RAS access can also be imple-
mented using the T-Comfort 930 DSL, which enables the integration of external staff in the LAN.
In this chapter you will find several examples of configurations showing integration of the T-Comfort 930 DSL
in a LAN. Which example applies to your situation depends on the size and properties of the existing or
planned LAN infrastructure.

Introduction to TCP/IP
In a single LAN it is possible to use various protocols for the transmission of data. The connection between a
workstation computer and the T-Comfort 930 DSL runs via the IP protocol (also named TCP/IP) used on the
Internet. IP can be used together with other protocols (e.g. NetBEUI, AppleTalk or IPX/SPX) on the same
network.
Every device participating in data transmission using IP requires a unique IP address. An IP address consists
of four groups of digits from 0 to 255, each separated by a full stop. The supplementary protocols DHCP and
PPP automatically assign IP addresses to devices. Class C networks normally use IP addresses in which the
first three numbers are the same and the last number is uniquely assigned to a specific device in the LAN. On
the Internet, unique addresses assigned by a special organisation created for this purpose are used. Within a
LAN, you can use addresses which are not unique world-wide:
IP Range Common Netmask Comment
192.168.0.0-192.168.255.255 255.255.255.0 256 smaller networks
172.16.0.0-172.31.255.255 255.240.0.0 1 medium network
10.0.0.0-10.255.255.255 255.0.0.0 1 large network
66
T-Comfort 930 DSL in a Serverless LAN Configuration Examples
IP enables the establishment of connections via one or more intermediate stations. The decision whether to
connect directly or indirectly to the partner device depends on the network mask. The network mask for a
class C network is 255.255.255.0. If the IP address of the partner device does not fit the network mask, the
connection is established via the default gateway. If a device knows several data routes to different interme-
diate stations, one speaks of a router.
The domain name system (DNS) resolves a plain text DNS name into an IP address. The DNS is a hierarchi-
cally structured database, distributed worldwide. A DNS server can supply information on the names and IP
addresses for which it is responsible. For all other information, a DNS server contacts other DNS servers. For
the establishment of every connection from the workstation, it is possible to give either an IP address, or a
name that a DNS server resolves into an IP address.
Note: For further explanations of technical terms, refer to the Glossary on the CD
N
supplied.
T-Comfort 930 DSL in a Serverless LAN
In a peer-to-peer network, the workstations are connected to one another via network cables. In many net-
works, the cables run in the form of a star from a central hub or switch. Such networks do not require special
servers. This configuration example is also valid for a LAN with a server using a protocol other than IP (e.g.
AppleTalk or IPX/SPX).

The T-Comfort 930 DSL in a serverless LAN
67
Configuration Examples T-Comfort 930 DSL in a Serverless LAN
In a serverless LAN, the T-Comfort 930 DSL takes over the IP configuration of the connected workstations. All
IP settings necessary for the workstations are assigned by the T-Comfort 930 DSL via DHCP (dynamic host
configuration protocol). In this operating mode, an IP address space reserved for such networks is used:
192.168.99.254 T-Comfort 930 DSL IP address
255.255.255.0 Network mask (class C network)
192.168.99.254 DNS server IP address
192.168.99.254 Default gateway IP address
Install the IP network protocol and a Web browser for every workstation which is to have access to the
T-Comfort 930 DSL network features.
DNS Name Resolution
In a serverless LAN, the internal DNS name resolution is performed by the T-Comfort 930 DSL. If you type the
string “host.domain” into your browser, a DNS request is sent to the T-Comfort 930 DSL IP address. The
T-Comfort 930 DSL responds with the correct IP address, so that the Configurator home page can be called
up.
In a peer-to-peer network (Windows network), the workstations each have a name which is displayed in the
network environment. These NetBIOS names can differ from the DNS names assigned to the workstations by
the T-Comfort 930 DSL. The T-Comfort 930 DSL is not visible in the network environment.
Internet Access
If access to an ISP has been configured on the T-Comfort 930 DSL, the T-Comfort 930 DSL can be operated
as an Internet access server without any additional configuration of the workstations. When you want to see a
Web page, you simply type the URL (uniform resource locator; Internet address; “http://...”) in your browser. In
a serverless LAN, the T-Comfort 930 DSL is configured as a DNS server and default gateway. The workstation
therefore sends its Internet connection request to the T-Comfort 930 DSL.
68
T-Comfort 930 DSL in a Serverless LAN Configuration Examples
In almost all cases, the request will contain a DNS name which is unknown in the internal network. When you
type a URL into your browser, the T-Comfort 930 DSL receives the request to find the corresponding IP
address. If the name is unknown in the LAN, the request is forwarded to an ISP’s external DNS server.
N
RAS Access
You can establish a connection to the T-Comfort 930 DSL from an external PC via an ISDN card.
The necessary IP settings are transmitted by the T-Comfort 930 DSL on establishment of the connection. The
computer that has dialled in has access to all services in the LAN that can be used via the IP protocol. The
authorisation for RAS access is set up in the Configurator via the User Manager: User Groups menu.
The technical properties of the connection can be configured in the Configurator via the NET Configuration:
Note: Workstation PCs automatically add a domain name to URLs without a dot. You
specify this domain name in the Configurator. For example, if you have configured
“firm.co.uk” as the domain name, an access request for “www.firm.co.uk” will be inter-
preted as a local DNS request which does not lead to the establishment of an Internet
connection. For this reason, you should choose a name which is not used in the Inter-
net as the domain name (“my-firm.co.uk” for example).
RAS menu. Further information can be found in the online help of the web console.
In a serverless LAN, Windows uses the NetBIOS protocol for accessing files and printers via the network envi-
ronment. NetBIOS can use NetBEUI, IPX/SPX or IP as the transport protocol. In the network environment, you
can only access files and printers on workstations using IP for NetBIOS.

In a LAN with an IP-enabled server, you should coordinate integration of the T-Comfort 930 DSL with the
responsible network administrator. You must decide on the IP address space to be used and which network
services (DHCP, DNS, RAS, Internet access) the T-Comfort 930 DSL is to handle in the LAN.

The T-Comfort 930 DSL in a LAN with an IP-enabled server
In many cases, an IP-enabled server configures the IP settings via DHCP for all workstations. On starting, the
T-Comfort 930 DSL requests IP settings via DHCP. If this request is responded to, the T-Comfort 930 DSL
uses the IP settings received. You can then use a workstation to access the T-Comfort 930 DSL Configurator
under the IP address assigned by the server.
In networks in which the IP settings are made manually, you have to enter the corresponding IP settings in the
T-Comfort 930 DSL Configurator (NET Configuration: LAN menu). Here the T-Comfort 930 DSL acts as the
DHCP server. A workstation requesting the IP settings via DHCP then receives the settings you made in the
Configurator.
70
T-Comfort 930 DSL in a LAN with an IP-enabled Server Configuration Examples
DNS Name Resolution
In a LAN with an IP-enabled server, the latter is also responsible for DNS name resolution. If you want to start
the Configurator by entering a DNS name, you must link this name on the server with the IP address used by
the T-Comfort 930 DSL. For further information, refer to the server documentation.
Note: To access the T-Comfort 930 DSL under the same IP address after a restart, you
N
must specify this IP address permanently on a DHCP server. On a DHCP server it is
find details in the server documentation.
Internet Access
You can also use the T-Comfort 930 DSL as an Internet access server in a LAN with an IP-enabled server. To
do this, you must enter the T-Comfort 930 DSL IP address on the server as the default gateway. In addition,
you must edit the internal DNS server configuration so that the resolution of external DNS names is forwarded
to the T-Comfort 930 DSL.
In this example, the Internet connection is established from a workstation via the server, which in turn
requests Internet access from the T-Comfort 930 DSL.
There are two different ways of suitably configuring the internal DNS server. You can enter the T-Comfort
930 DSL IP address as a DNS forwarder. If you require access to extended DNS information, you can also
configure the DNS server for a recursive DNS request without the DNS forwarder. For further explanation,
refer to the DNS server documentation.

The user account administered by the T-Comfort 930 DSL, with which dialling in is permitted, only allows the
establishment of direct and anonymous TCP/IP connections such as HTTP, FTP or SMTP connections. If you
additionally want to allow file or printer access in the network, you must set up a suitable user account on the
addressed server for network log-in. If you use the same log-in name for the T-Comfort 930 DSL user account

Note: In a larger Windows network with several segments, the lists of computer names
visible in the network environment can no longer be established by broadcasts. In this
case you use a special WINS server whose address the T-Comfort 930 DSL does not
make known to the workstation when dialling in with ISDN. For this reason, you enter
the address of a WINS server manually in the network settings of the workstation.
Branch Link
You can use the T-Comfort 930 DSL to interlink two LANs via ISDN.
To do this, you configure two T-Comfort 930 DSL systems so that they can dial in to each other.
In order for this to work, the two LANs must be configured for different IP address ranges (subnetworks). For
at least one of the T-Comfort 930 DSL systems, change the prescribed address range for the LAN.

Note that such a connection is only set up when specific requests are made. These can be for FTP file
transfers, e-mails or downloading Web pages. Name resolution via broadcasts is not possible. If you wish to
use the LAN-to-LAN link to access files and printers in the Windows network, you need an IP-enabled server
that administers the name resolution for the Windows network.
As the IP address range, you can select one of the 256 class C subnetworks designed for local LANs. Select a
class C sub-network in the range from 192.168.0.0 to 192.168.255.0.
Useful Information on Internet Access
Costs
The T-Comfort 930 DSL uses a router function to access the Internet, which means that it automatically estab-
lishes an Internet connection when required and terminates the connection after a certain period of time if no
data are being transmitted.
Unfortunately, programs other than those typically intended to access the Internet (such as your browser or
your e-mail software) may send out data packets which cause an Internet connection to be established, even
if these programs are not strictly Internet-associated applications.
Examples of such programs are the Microsoft
as Realplayer
(the so-called “phone home function”).
It is therefore highly advisable to limit ISP access by specifying the maximum monthly connection time under

the browser. Access from a stand-alone PC via an online service differs from Internet access via the T-Comfort
930 DSL in the following respects:
■ When you request a Web page, dialling in results automatically. There is no display of dialogues with
manual confirmation of dialling in or hanging up.
■ Requesting Web pages is not a connection-orientated service. When the Web page has been loaded
completely, the TCP/IP connection is cleared. If you do not request further Web pages, the T-Comfort
930 DSL automatically releases the connection to the Internet after a certain, specifiable duration.
■ It is possible to call up Web pages simultaneously from several workstations.
■ The T-Comfort 930 DSL can block access to certain Web pages by means of filter lists.
E-mail
One of the most important services in the Internet is e-mail. E-mails are buffered in individual e-mail accounts
on a mail server. Mail servers are operated by ISPs for example. With the T-Comfort 930 DSL you can set up
one or more e-mail accounts for every user account configured on the T-Comfort 930 DSL. These e-mail
accounts are then checked at regular intervals.
If there are new e-mails in an e-mail account, and the T-Comfort 930 DSL has been configured for this
function, the user specified in the T-Comfort 930 DSL user account is notified of the new e-mail on his system
terminal. T-Comfort 730/830 DSL system telephones can also display information such as the sender or the
subject of the e-mail.
NAT
Network address translation (NAT) is activated on accessing the Internet (ISP). You require this feature in
order to translate internal IP addresses to valid external IP addresses. This has three important consequences
for Internet access:
■ Several workstations can share a single Internet access. You do not require a LAN access, only a single
account with the Internet service provider.
75
Configuration Examples Useful Information on Internet Access
■ The IP addresses used in the LAN are translated into IP addresses valid worldwide. So you require no
such addresses for your LAN.
■ Only IP connections triggered from a workstation can be established. Consequently, while you can call up
Web pages from a workstation, you cannot install a Web server visible in the Internet on a workstation.
Certain protocols cannot be used when NAT is being used. This affects protocols with the following prop-
erties:
■ IP addresses are transported in the useful load, e.g. NetBIOS over TCP/IP.
■ The protocol requires an active, inward-directed connection establishment, e.g. ICQ.
■ The protocol will function without TCP/UDP port numbers, e.g. ICMP or IGMP.
The T-Comfort 930 DSL NAT has suitable processes for ensuring the functions of many important protocols
affected by these rules. These are the protocols FTP (in “active” mode), CuSeeMe (“videoconferencing”), IRC
(“chat”), ICMP errors (“traceroute”) and ICMP echo (“ping”).
Protocols which require inward-directed connection establishment can be configured in the Net Configu-
ration: Port Access menu. For further information, refer to the online help of this menu.

Variants of PBX Cascading PBX Cascading
PBX Cascading
As requirements grow, the T-Comfort 930 DSL can be operated together with other PBX installations. If you
merely need a larger number of connections, it is easy to link a second PBX (PBX Cascading). If you want to
operate the T-Comfort 930 DSL at several locations with different PBXs, this is possible by PBX Networking
(see page 81).
Variants of PBX Cascading
You can combine two PBXs in order to increase the number of terminals that can be connected. A master
PBX and a slave PBX are connected to one another by means of two cables. The two PBXs essentially
function like a single PBX with a higher number of ports. The master PBX controls the slave PBX. The fol-
lowing PBXs from the product family can be used for cascading:
Master system Slave system
T-Comfort 930 DSL T-Comfort 930 DSL
Functionality of PBX Cascading
PBX cascading requires two twisted-pair leads with RJ45 plugs between the PBXs:
■ Voice data: one lead with all eight pins wired 1 to 1. Connect this to the PCM ports of the PBXs. The
shielded CAT-5 lead may be up to three meters long.
The PCM port is on the add-on module of the T-Comfort 930 DSL. You must therefore install an add-on
module in each of the two PBXs before they can be cascaded.
■ Administration data: one CAT-5 Ethernet lead.
Connect the LAN2 port of the master system’s add-on module with a LAN2 port of the slave system’s add-
on module.

3. Switch off the master system if it is operating. Disconnect the module from the power supply by pulling
out the mains plug.
4. If necessary, install the add-on module for the master system. If you use an T-Comfort 930 DSL as the
slave system, you also have to install an add-on module.
5. Connect the two modules by means of two suitable cables as described above.
6. Power on the two PBXs. The order in which you do this does not matter.
7. In the PBX Configuration: Ports: Slots dialogue of the master system’s Configurator, click on Slave.

Connections PBX Networking
PBX Networking
T-Comfort 930 DSL provides all the features necessary for PBX networking. You need PBX networking in the
following cases:
■ To operate the T-Comfort 930 DSL as a subsidiary system on another PBX. This will also allow you to use
the T-Comfort 930 DSL as a DECT server, for example.
■ To network several T-Comfort 930 DSLs into a PBX system.
■ To use flexible configuration possibilities of trunk lines for a T-Comfort 930 DSL.
All settings that affect the configuration of PBX networking can be found in the Configurator menu
PBX Configuration: Trunks and in the PBX Configuration: System: Settings dialogue under System
linking. Refer also refer to the corresponding help topics in the T-Comfort 930 DSL online help.
Note: If you do not need the features of PBX networking, the simplified configuration is
N
sufficient in most cases. For this purpose, assign the preconfigured trunk groups (bun-
dles) Multi-terminal access or System access to the ports. The preconfigured route
called External trunk now makes it possible to seize an external line immediately or by
first dialling the prefix “0”. You can rename the preconfigured bundle and the preconfi-
gured route if required, but you cannot delete them.
Connections
Networking two or more TK systems means interconnecting them. The T-Comfort 930 DSL allows you to use
the following connections:
■ ISDN trunk lines
■ ISDN point-to-point connections (Q.SIG) on external S
ports
0
81
PBX Networking Connections
PBX PBX PBXPBX
PBX
Trunk line Point-to-point connection
Example of a PBX network
Various line types and transmission protocols can be used for point-to-point connections. The required
network topology (distance, connection capacity) determines which type of point-to-point connection is most
suitable.
Protocol: Q.SIG or DSS1
The Q.SIG protocol, designed for ISDN point-to-point connections, is the preferable choice as the trans-
mission protocol; alternatively, the DSS1 protocol, designed for ISDN dial-up connections in the Euro-ISDN,
can be used. Certain PBX networking features can only be used with the Q.SIG protocol, however. In par-
ticular, the identifier indicating whether a call is internal or external cannot be transmitted using DSS1.
Both protocols implement communication on several protocol layers:
■ L1: Layer 1 defines the physical line properties and the electrical coding of signals.
■ L2: Layer 2 enables communication via individual error-protected channels that are independent of each
other.
■ L3: Layer 3 defines the administration of the individual channels and implements the features designed
for ISDN.
Master/Slave
For an ISDN connection, it is possible to determine which PBX is the protocol master and which the protocol
slave. This relationship can be determined for all three protocol layers independently of one another.
82
Connections PBX Networking
For each protocol layer, the PBX at the other end always has to be suitably configured. If one PBX is the pro-
tocol master for a layer, the other PBX must be the protocol slave for this same layer. Normally all three pro-
tocol layers are configured identically. In the case of a trunk line, the network operator is the protocol master
for all three layers.
L1 Clock
To enable PBXs in the ISDN network to communicate with each other, they must be “clock-aligned”. The L1
protocol master sets the clock for layer 1, and the L1 protocol slave adopts (synchronises to) this clock.
When planning a PBX networking scheme, you must make sure that the L1 clock propagates from a master
via a number of PBXs.

Example: propagation of the L1 clock
If more than one port with the setting L1 Type = “Slave” is configured on anT-Comfort 930 DSL and the
setting L1 sync possible has been activated, then one of the ports is automatically defined as the L1 clock
source. The T-Comfort 930 DSL will automatically switch the clock source to another port configured as an
L1 clock source (if a line fails, for example).
S
Please note: Reciprocal or circular application of the L1 clock is not allowed.
Example: In the above case you could reverse the L1 slave/master setting for the connection between PBX 1
and PBX 3. However, if you then activate the setting L1 sync possible for the port of PBX 1, this may cause
parts of the PBX network to stop functioning temporarily.
When applying the L1 clock of trunk lines, you can assume that the public network is “clock-aligned”. So, in
the above example, you can connect additional trunk lines to one of the PBXs.

PBX Networking Types of Point-to-Point Connections
Types of Point-to-Point Connections
There are different types of connection available for an point-to-point connection between two PBXs,
depending on the distance between them.
Direct Connection
This type of ISDN point-to-point connection joins the two systems directly to each other using a crossover
twisted-pair cable. An S
connection can be used for distances up to 1,000 metres. Normally one PBX is the

Wiring of a direct connection
Types of Point-to-Point Connections PBX Networking
Connection via an Active Transmission System
For distances exceeding the range of a direct connection, an active transmission system can increase the
range to up to 50 km. Normally the L1 master is the transmission system for the two connected PBXs. For the
protocol layers L2 and L3, one PBX is normally the protocol master and the other PBX is the protocol slave.

Connection via the Public Network
Point-to-point connections via the public network of a network operator can be used for bridging distances
beyond 50 km. Due to the long distance involved, for technical reasons it is not possible to synchronise the L2
protocol. Consequently, the public network is normally the protocol master for protocol layers L1 and L2. One
PBX is therefore the L3 master and the other PBX the L3 slave.

Routes
A route is a group of trunk groups enabling a connection in one direction. If the first trunk group of a route is
fully utilized, the next trunk group is seized (“trunk group overflow”). One trunk group can also be used for dif-
ferent routes.
In the above example, a route set up for PBX 1 allows a connection to PBX 2. Trunk groups “C,” “E” and “A”
are assigned to this route. If a user connected to PBX 1 wants to reach a party in PBX 2, lines will be seized in
the following order:
■ PBX 1 first searches for a free channel in the “C” trunk group.
■ If all the lines in trunk group “C” are busy, the system tries to set up a connection via trunk group “E”.
PBX 3 switches the connection through, provided it is appropriately configured (refer to Numbering
starting on page 87).
■ If it was not possible to set up an indirect connection via PBX 3, the system tries again via trunk group “A”.
The “prefix” necessary for this can be configured with the route.
■ The user does not get a busy signal until the attempt to set up an indirect connection via the network
operator has also failed.
N
For each route you can define a randomly selectable code digit for seizing the route. You can also configure
whether a user is authorised to seize a particular route, whether LCR is to be used for one of the trunk groups.
Numbering
Note: If an internal connection is switched via a network operator, the call is signalled
using the external number of the calling PBX.
A user can seize a particular route by pre-dialling a specific code digit. With this “open numbering”, a user
must always dial this code digit and then the telephone number in order to reach a party in another PBX.
If none of the telephone numbers in your PBX network occur twice, you can also configure “closed num-
bering”, allowing the same telephone number to be used for reaching each user within the PBX network.
87
PBX Networking Technical Details
With closed numbering, the T-Comfort 930 DSL determines which route to seize from the telephone number
dialled. The information needed for routing a call can be configured in a numbering table containing up to
100 entries. You use this table to assign telephone numbers and/or ranges of telephone numbers to a par-
ticular route.
A default entry in the numbering table makes it possible to seize a “default route” for all remaining unas-
signed numbers. In particular, this simplifies configuration of the T-Comfort 930 DSL as a subsidiary system:
the only entry you assign to the default entry is the route to the host system

Example of closed numbering tables
The automatic switching of call requests (i.e. routing) by means of trunk group overflow or default numbering
can lead to “circular switching”.
To avoid this, a “transit” counter is incremented whenever a connection is switched through on Q.SIG lines.
When the configured maximum value is reached, further switching stops.
Technical Details
A different PBX number must be set for each T-Comfort 930 DSL in a PBX network. This setting can be found
in the Web console, in the menu PBX Configuration: System: Settings under the heading System linking.
You can also set the maximum value for the transit counter there. This value depends on the topology of the
PBX network and should allow the system to have the maximum number of further connections possible.
You can display the connection status of the lines at any time in the Configurator menu System info: PBX:
Trunks. You should check this in particular after making changes to a configuration to see whether all the
lines used for system networking are operable.

Some of the features possible in Q.SIG are not supported by T-Comfort 930 DSL with all their options, for
example callback on busy within the Q.SIG network. The call categories defined in Q.SIG (e.g. Emergency
Call, Operator, Normal) and the Q.SIG name transmission feature (“user names”) are fully supported.
The code digits to be used for seizing a route with open numbering are not transmitted to the destination PBX
and thus cannot be evaluated by it. To reseize a route (for example for a callback), you must set the appro-
priate digit prefixes in the trunk group configuration for the routes to be reseized.

Team Functions Introduction
Team Functions
Introduction
With the team functions you can manage your telephone communication tasks by assigning lines with sep-
arate call numbers to the keys of different terminals. The terminal users, or team members, can thus pick up
one another’s calls or telephone each other using the configured keys.
Team functions can only be configured on the T-Comfort 630/730/830 and Comfort Pro P 100/300/500
system telephones because only these have the required features.
Explanation of Keys
The team functions are programmed on the call keys of the T-Comfort 630/730/830 telephones. Depending
on the terminal, different numbers of call keys are available:
System telephone Number of keys
T-Comfort 630 One key with a display, five keys without a display
T-Comfort 730 Three keys with a display, five keys without a display
T-Comfort 830 Nine keys with a display
T-Comfort 830 with an additional keypad module 19 keys with a display: nine on the telephone itself
and 10 on an add-on keypad module
Comfort Pro P 100 One key with a display, five keys without a display
Comfort Pro P 300 Three keys with a display, five keys without a display

The following keys can be used:
■ Trunk key: Calls (for the programmed call number, e.g. 11) are signalled to this key, and you can make
internal and external calls via this number. A trunk key can be programmed with a substitute function
(with another team member acting as the substitute). Calls for you are then signalled to the terminal of
another team member. A trunk key also provides functions for managing calls. For example, you can con-
figure call protection if you do not want to be disturbed, or call diversion to another telephone.
■ Team key: As with a trunk key, a team key can be used to receive or make calls. However, this key cannot
be used to change the settings for managing calls; it is not possible, for example, to configure call
diversion to another telephone. Calls made via a team key are signalled to all terminals with a trunk key
that has been programmed with the same number. For example, the team key with the number 11 calls all
trunk keys with the number 11.
■ Busy key: The purpose of a busy key is to make the busy status of other team members visible. An
incoming call for a busy team member is signalled on the other team member's busy key. That team
member can take this call by pressing the busy key, which seizes his own terminal's trunk key. Calls taken
via the busy key are not entered in the call list of the team member who was originally called. In addition, it
is possible to call the respective team member via his busy key when his terminal is idle. You set up a call
to this team member by pressing your own trunk key.
91
Team Functions Examples of Use
■ Direct call key: Only outgoing calls can be made with a direct call key; they are signalled to all terminals
with the same number programmed to a trunk key. Calls via a direct call key are signalled to the desti-
nation terminal even if that terminal has been programmed with a substitution function or call protection.
If the destination terminal has been configured for call diversion, the direct call is not diverted.
Which key is suitable for which purpose?
■ Trunk keys can be assigned call numbers for managing central communication tasks, for example, cus-
tomer support. If the call numbers of the support department are assigned to trunk keys on all of its ter-
minals, then all members of the support department can receive and manage calls and use the substitute
function.
■ Team keys, for example, can be used to create a project group within a department. Calls from customers
of this group can then be answered by any team member who is not busy. The team members can call
each other by the team keys.
■ A busy key can be used to configure an enquiry station showing the status of the individual users. The
enquiry station sees the status of the users and can put calls through by simply pressing the key.
■ Direct call keys, for example, can be configured at a terminal in a conference room to call the secretary.
Team Configuration
You can create teams and program call keys in the Configurator of the T-Comfort 930 DSL (PBX Configu-
ration: Groups and Ports: Upn menu).
Call key 1 is preset as a trunk key on all system telephones. This setting can be changed by the system admin-
istrator.
Examples of Use
The following examples illustrate the various uses of teams and team functions.

Line Seizure
The secretary can be reached on the call number 11 (trunk key TrK 11: secretary’s office).
The executive can be reached on the call number 10 (trunk key TrK 10: executive’s office). He can also
Executive´s Parallel
TrK 10: Executive
TrK 12: Private
answer calls from his parallel telephone. In addition, a private line is configured for both of the executive’s tel-
ephones (trunk key TrK 12: private).
Call numbers 11 and 10 are both configured as a trunk key on the executive’s and the secretary’s terminal
respectively. Thus the executive and the secretary can use either call number (for answering as well as
making calls). Each can act as a substitute for the other.

Team Functions Examples of Use
The secretary’s terminal also has the executive’s call number configured as a direct call number (DK 10: exec-
utive’s office). The secretary can therefore reach the executive and put through calls even if the executive has
programmed a substitute.
Line Busy Indication
If a line is busy, e.g. TrK 11 secretary’s office, the other terminal will indicate this. The executive’s private calls
via TrK 12 are not indicated on the secretary’s terminal since no appropriate trunk key is configured on the
latter’s telephone.
Call Signalling
In this configuration example, calls to one’s own call number are signalled acoustically on the following tele-
phones:
■ Call number 11 on the secretary’s telephone
■ Call numbers 10 and 12 on the executive’s telephone.
Calls for the other team member’s call number are indicated by an optical signal on one’s own telephone
(flashing trunk key LED).
The parallel telephone will indicate calls only by an optical signal.
Time-delayed acoustic signalling can be configured for TrK 10 on the secretary’s telephone. If the executive,
for example, does not answer a call within 10 seconds, the secretary’s telephone will start to ring.
If the executive activates a substitute function with the secretary as the substitute, calls for call number 10 will
be indicated on the executive’s telephone by an optical signal only, but signalled acoustically on the sec-
retary’s telephone. The secretary can also activate a substitute function. Calls for call number 11 are then sig-
nalled acoustically on the executive’s telephone, and indicated by an optical signal on the parallel telephone
and the secretary’s telephone.
Three-member Team
The three-member team described here is an example of a team configuration within a project group, e.g.
export sales.
Each team member has one T-Comfort 730 system telephone with all call keys programmed as trunk and
team keys.

Example: three-member team
Line Seizure
Each team member’s call number, e.g. call number 10 for Miller, is programmed as a trunk key on his tele-
phone.
On the other telephones in the team, this call number is programmed as a team key (e.g. TK 10 on Johnson’s
and Smith’s telephones). The team members can thus see which number a call is for and can answer it by
pressing the appropriate team key.
The team members can call each other via the team keys. For example, Miller can call number 12 by pressing
TK 12; the call is then signalled to Smith’s telephone on TrK 12.
Line Busy Indication
If a line is busy, e.g. TrK 11 Johnson, the team keys 11 on Miller’s and Smith’s telephones will indicate this.
Call Signalling
In this example, calls via the trunk keys are signalled acoustically. Calls via the team keys are indicated by a
visual signal (the team key LED flashes).

Team Functions Examples of Use
Unified Team
The unified team described here is an example of a team configuration within a department in which calls are
to be managed quickly (e.g. support department).
Each team member has one T-Comfort 730 system telephone with all call keys programmed as trunk keys.

Example: unified team
Line Seizure
Call numbers 10, 11 and 12 are programmed as trunk keys on each team member’s telephone (TrK 10
toTrK 12.
All team members can use these numbers for answering as well as making calls.
In this team configuration it is useful to program one of the function keys on each tele-
t
phone with the “Hold” function. A call, e.g. for TrK 11, can then be put on hold by
pressing the function key. If another team member then presses trunk key TrK 11 on
his telephone, he can accept the call. For further information on function keys, refer to
the “T-Comfort 630/730/830” and “Comfort Pro P 100/300/500” user guide.

Line Seizure
Each team member is assigned two call numbers, each programmed as a trunk key (LT 10 to LT 15).
97
Team Functions Examples of Use
The first number of each team member is programmed as a team key on the other member’s telephone, e.g.
LT 10 on Miller’s telephone as TT 10 on Johnson’s telephone. The assumption here is that most calls will go to
the respective first call numbers, and team members can thus help each other out by answering one
another’s calls.
On each telephone it is possible to toggle between the calls on individual lines, e.g. TrK 10 and TrK 11, by
pressing the appropriate key (toggling).
Every call on a trunk key can be transferred to any other party by means of the R key. For more information,
refer to the chapter entitled “Consultation, Toggling, Transfer and Conference” in the “T-Comfort 630/730/
830” and “Comfort Pro P 100/300/500” user guide.
Line Busy Indication
If a line is busy, e.g. TrK 10 on Miller’s telephone, the appropriate team key will indicate this, e.g. TK 10 on
Johnson’s telephone.
Call Signalling
In this example, calls via trunk keys are signalled acoustically. Calls via team keys are indicated by a visual
signal (the team key LED flashes).
