Snom D7C User Manual Setting up the expansion module
Connecting the Snom D7C to a Snom phone
The connectors are marked A, B, and C. Connectors A and B are used to attach the footstands of D7C
and the phone, connector C is used to connect the footstands of two D7Cs:
◦A: connecting to D717, D735, and D765.
◦B: connecting to D785. There is also a smaller plate marked B to connect the D7C and the
D785 more securely.
◦C: connecting a D7C to another D7C.
You can connect up to three Snom D7Cs to one of the supported Snom phones. The rst expansion
module is supplied with power by the phone via the module's USB cable. The second module is
supplied with power by one of the separately available power adapters. The third expansion module
is supplied with power by the second module via the third module's USB cable.
Note: In some cases, e.g. if you connect a device requiring a lot of power to the USB
port of the D7C, you may also need to attach a power adapter to the third and the rst
module in the daily-chain.
1. Place a soft cloth on the desktop so that the display does not get scratched or otherwise damaged
if you lay the device down.
2. Attach the respective footstand to the D7C expansion module and to the phone.
3. Place the USB cable of the D7C into the cable guide (Fig. 1).
Fig. 1
4. Connect the expansion module to the phone, as shown in Fig. 2. If the phone has two USB ports
(Fig. 3), either one can be used.

5. Holding the D7C and the connector backside up, push the connector against the footstand of
the DC7 (Fig. 4). If it does not snap securely into place, push the three levers on the connector
towards the footstand of the D7C until you hear each one click into place (Fig. 5).
Fig. 4 Fig. 5
6. Push the other side of the connector against the footstand of the phone. If it does not snap
securely into place, push the three levers on the connector towards the footstand of the phone
until you hear each one click into place.
7. D785 only. Place a soft cloth on the desktop and turn phone and D7C backside up. On either side
of the small plate marked B there is a ridge (Fig. 6) that ts into the slideguides on the footstands.
Insert the ridges into the slideguides of the footstands of phone and D7C and slide the connector
down toward the tips of the "legs" (Fig. 7).
Fig. 6 Fig. 7
Connecting two or three D7Cs to a Snom phone
Do not use a USB hub (Fig. 8). If the phone has more than one USB port, do not connect expansion
modules to more than one port (Fig. 9). The D7Cs must be daisy-chained. If they are not, the phone
will not be able to identify the function keys on the modules, rendering them inoperable.
Fig. 8 Fig. 9
1. Connect the modules to each other rst. If a module is connected to the phone already, connect
the second and third module to each other.
2. Important note: Attach a power adapter (available separately) to the second module and to a wall
outlet before connecting the daisy-chain to the phone or the second / second and third module to
the D7C already connected to the phone (Fig. 10).

Detaching the connector
Push the three levers on the respective side inward to detach the connector from the footstand.
Connecting a wireless headset
On phones with a single USB port, the USB port on the expansion module can be used to connect a
wireless headset via its USB adapter. If two or three expansion modules are daisy-chained, insert
the USB adapter of the wireless headset into the USB port on the last module in the chain,
If the Snom phone has two USB ports, the USB adapter of the wireless headset can be inserted into
the USB port on the expansion module or into the free USB port on the phone.

XML provisioning of settings
The XML tags of the function keys are an exception from the general rules for XML mass provisioning
of settings for Snom phones because the tag for each key species the exact settings for that
particular key. The format is as follows:
<fkey idx="n" context="active" label="x" default_text="$name $state" perm="">argument</fkey>
Example:
<fkey idx="33" context="active" short_label_mode="text" short_label="" short_default_
text="!!$(::)!!$(generate_via_conditional_label_short)" label_mode="icon_text" icon_type="" reg_
label_mode="icon_text" label="" lp="on" default_text="!!$(::)!!$(generate_via_conditional_label_full)"
perm="" c="1" cslm="1" clm="1">dest &lt;sip:[email protected];user=phone&gt</fkey>
For more information on function key types, see https://service.snom.com/display/wiki/
Function+Key+Types. For more information on valid values and defaults, see the individual settings
at https://service.snom.com/display/wiki/Settings.

Snom D7C User Manual Conguring the function keys
• Parameter fkey idx. The unique identier of the function key when connected to a particular
phone model.
NOTE: The fkey idx of a particular key depends on the number of function keys on the
phone, the number of expansion modules connected to the phone, and the position of
the module in the daisy chain. For your convenience, we have prepared a table of the
numbering system; please see "Function key numbering system" on page 20.
• Parameter context. This setting species the identity (account) that can use the key. The default
is Identity 1. Valid settings:
◦All active identities (accounts) registered on the phone: Setting "active".
◦One identity specied by its number. Example: Setting "1" for Identity 1.
• Parameter label. The label (name, etc.) to be shown on the expansion module's display. On the
Function Keys page of the phone's web interface this is the string entered in the text eld of
Label. See "SmartLabels" on page 11.
Examples for an extension setting.

• Parameter default_text. Optional attribute that can be any string. When the parameter label is
not set for a key, the value of default_text will be displayed as the key's label on the display of
the D7C (see "Display layout" on page 10). You can dene an arbitrary xed text or use $name,
$state, and $type to insert dynamic information. The default value is "$name $state".
◦ $name: Inserts the label or, if label is not set, the extension/phone number supplied as the
key's argument.
◦ $state: Inserts the key's state (free, busy, etc.) when functions like line or extension are
mapped onto the key.
◦$type: Inserts the key type.
• Parameter perm. Valid values are:
- perm="!": The settings of the key can be changed by mass provisioning, but only if the
end user has not made changes to the conguration on the phone itself or on its web
interface.
- perm="&", perm="R", perm=" ": The settings of the key are Read Only and cannot be
changed by the end user.
- perm="$", perm="RW", perm="": The settings of the key can be changed by mass
provisioning; any end user congurations will be overwritten on reboot.
• Argument.
◦ The default is line. Example:
<fkey idx="19" context="1" label="" default_text="$name $state" perm="">line</fkey>.
◦Examples for other functions:
NOTE: These settings depend on the requirements of the PBX.
- Extension: <fkey idx="19" context="1" label="Mary" default_text="$name $state"
perm="">dest sip:[email protected];user=phone</fkey>
- Speed dial:
<fkey idx="20" context="1" label="Mary/cell" default_text="$name $state" perm="">speed
