1.1.1
PART 1. OVERVIEW
This part of the technical manual is titled “Special Applications” because it provides
information about interfacing with customer-provided equipment or using a feature in a
different way than it was intended. Perhaps an application may require a combination
of CPE, creative programming, unusual feature operation or all of the above.
Because these applications require installation instructions and a combination of
programming sequences, there is no obvious place to put this information; therefore,
we created this part of the manual. As additional special applications are reported from
the field, we will include them in this section.

PART 2. APPLICATIONS
2.1 INDIVIDUAL STATION PAGE
The system was not designed to permit page announcements to individual keysets.
However, a forced auto answer key (FAUTO) can be used to accomplish this objective.
1. Program a keyset for RING in MMC 103.
2. Assign an FAUTO key to each keyset that is allowed to page individual keysets.
3. Call another station. When you hear ringback tone, press the FAUTO key. The
ringing will stop and an Auto Answer call is set up.
NOTE: To prevent the use of this feature from getting out of control, only assign FAUTO
keys to those keysets needing to page individual keysets.

2.2 CALLER ID
The OfficeServ 7100 is compatible with both types of Caller ID as defined by
BELLCORE. These are the single message format or “Number Only” sometimes
referred to as standard Caller ID and the multiple message format or “Name and
Number” sometimes referred to as Deluxe Caller ID. In the case of Number Only
delivery, there is a translation table available that may be used to add names to the
delivered number.

SOFTWARE PROVISIONS
The MMCs related to Caller ID are listed below with a short description of their use.
They are listed in the recommended order in which they should be programmed. This
sequence is suggested so that the installer gets a better understanding of how the
feature works. There is no technical reason to follow this sequence.
zMMC 414 CALLER ID TRUNKS This MMC is used by the technician to determine
which trunks will receive Caller ID data.
zMMC 312 ALLOW CALLER ID This MMC is used by the technician to determine
which keysets are allowed to receive Caller ID
displays.
zMMCs 722 and 723 These MMCs have keys related to Caller ID
features added to them. It is strongly
recommended that all keysets allowed Caller ID in
MMC 312 are programmed with a CID key.
zMMC 728 CID TRANSLATION This MMC allows the technician to create a list of
names that correspond to numbers received from
the Central Office. These names will be displayed
when a call rings in that has NUMBER ONLY data
provided by the CO.
zMMC 725 SMDR OPTIONS The ability to print Caller ID data and abandoned
calls is determined by this MMC.
zMMC 119 CALLER ID DISPLAY The OfficeServ 7100 will display both Caller ID
Name and Number simultaneously on the display
the keysets. This MMC is used by the end user to

determine which piece of Caller ID data is
displayed when a call rings at the user’s station.
This MMC is primarily used when displaying
transferred calls.
zMMC 501 SYSTEM TIMERS This MMC has two new timers related to Caller ID.
The only timer that may need adjustment is the
CID DISPLAY TIME. This is the length of time that
CID data is displayed after the CID key is pressed.
zMMC 415 TRK. ABANDON This MMC is used by the technician to determine
which trunks will record data in the Call Abandon
list and print with an Abandon “A” flag on SMDR.
zMMC 608 ASSIGN REV BLOCK This MMC is used by the technician to assign CID
Review blocks to keysets to allow the user to
review CID data for previous calls.
zMMC 701 ASSIGN COS All of the Caller ID features have been added to
this MMC to enable the technician to allow or
deny them.
zMMC 724 NUMBER PLAN The Caller ID features have been added to this
MMC to allow a technician to assign an access
code where necessary.
In addition to the above MMCs, it is necessary to have LCR programmed on the system
to enable certain features with a DIAL/REDIAL option to be used. This is because the
number format provided by the Central Office contains the area code. This area code
must be stripped off in the LCR modified digits section to allow a local number to be
correctly dialed.
For example, if the system is located in the 305 area code, the LCR digit table points
the entry 1305 to a modified digits entry that deletes the first four digits of the CID
number. Of course, this is a much simplified LCR scheme. As there are long distance
calls to be made within the home area code, additional entries are required to identify
these.
For example, if 1305-426 is a local call, the area code has to be stripped, but if 1305-
858 is long distance, the area code has to remain to allow the number to be dialed.
There are two ways of doing this. You can either enter all of the local office codes and
tell the system to strip the area code from them or you can enter the long distance
codes and tell them to ignore the modify digits entry.
A list of all of the local office codes can be found at the front of the local telephone
directory.

2.3 USING LCR TO INSERT LONG DISTANCE
PICK CODE
One of the more common uses for LCR is to use this feature to automatically insert the
long distance access code for long distance calls within your own area code. This will
allow these calls to be processed by the selected long distance carrier instead of the
local telephone company. The following example is based on an area where all long
distance calls must be preceded by 1 + area code as this is the most common
scenario.
In MMC 710, program the following entries:

group automatically.
In MMC 210, turn on LCR.
Setting LCR up like this will not prevent C.O. lines from being accessed by Direct Trunk
(DT) keys but it does mean that speed dial numbers will have to be reprogrammed to
allow them to access LCR.

2.4 USING LCR WITH CALLER ID
It is necessary to have LCR programmed on systems with Caller ID to enable certain
features with a DIAL/REDIAL option to be used. This is because the 10 digit CID
number format provided by the Central Office always contains the area code. This area
code must be stripped off in the LCR modified digits section to allow a local number to
be correctly dialed. To make this task easier, the system inserts a 1 in front of the
received digits. This makes it look like a normal 11 digit telephone number so LCR can
process the number and modify the digits.
For example, if the system is located in the 305 area code, the LCR digit table points
the entry 1305 to a modified digits entry that deletes the first four digits of the CID
number. Of course, this is a much simplified LCR scheme. As there are long distance
calls to be made within the home area code, additional entries are required to identify
these calls. This is illustrated in the sample table for MMC 710 below where entries 013
to XXX are the local area code (305 in the previous example) followed by the local CO
prefixes. This will tell the system which calls need to have the first four didits stripped
off using the modifiy digits table.
In MMC 710, program the following entries:
MMC 710 LCR DIGIT TABLE

2.5 UNIFORM CALL DISTRIBUTION
UCD is used to distribute calls to a group of agents. If the group members (agents) are
all busy, UCD controls queue patterns and information messages. Callers are held in
queue for an available agent. First and second announcements reassure the caller
until an agent becomes free. The OfficeServ 7100 VM/AA ports are capable of
providing the UCD group overflow announcements. When VM/AA ports are used as a
UCD message source, the system provides the flexibility to share the ports with other
VM/AA applications, or dedicate these ports for play log UCD messages only.
The following step by step example demonstrated how to create an UCD application.
A SAMPLE UCD APPLICATION (STEP BY STEP)
1. Decide how many VM/AA ports you are going to use for UCD announcements.
Define these ports as a VMSUCD group in MMC 601. In this example we call this
group 505. The ring type should be distributed. Do not use the overflow, GRP
TRANSFER or NEXT.
2. In MMC 601, create a group (we use 525) defined as an UCD group and containing
the station numbers for the UCD agents. Set the group options as follows:
a. Set the ring type to DISTRIBUTED.
b. Set the overflow to ten seconds (creates a ten second ringback “grace period”
in case all agents are busy before the call overflows to the UCD module).
c. Set NEXT to 505.
d. Set the wrapup timer. This is an optional timer to allow UCD agents to finish the
work associated with a call before receiving the next call.
3. Decide what C.O. lines are to go to the UCD group and assign them to ring 525 in
MMC 406.
4. In MMC 607, program the UCD options. These consist of the following:
Message 1: After the caller has overflowed from the UCD group, the first message
will immediately play. The default value of ‘5061’ plays a default recording of “I’m
sorry, all stations are presently busy”. This message number can be assigned from
a valid range of 0001 to 9999 (corresponding to VM/AA prompts). Please refer to
Part 4 or Part 6 of the manual for customizing prompt recording instructions.
Message 2: If no agent has become free after the UCD recall time, the caller will be
played the Message 2. The default value of ‘5062’ plays a default recording of “I’m
sorry, all stations are still busy’. This message number can be assigned from a valid

range of 0001 to 9999 (corresponding to VM/AA prompts). Please refer to Part 4 or
Part 6 of the manual for customizing prompt recording instructions. This message
will repeat at the UCD recall interval.
Exit Code: This is an option that allows the caller to exit UCD by dialing this digit.
Retry Count: This is the maximum number of times that a caller will be recalled to
the UCD message before being transferred to the final destination.
Final Destination: The destination the caller will reach if the exit digit is dialed or the
retry count is exceeded.
Ring Next: This timer determines how long an unanswered call will ring a UCD
agent before that station is logged out and the next station in the UCD group rings.
UCD Recall: This timer determines the interval between UCD messages played to
the caller.
MOH: This determines the MOH source that the caller will be connected to while the
UCD recall timer is running.
AUTO LOG OUT: Determines if the ringing station will be logged out if the ring next
timer expires.
ALL OUT¤FINAL: Determines if calls will go directly to final destination if all agents
are logged out.
AGENT PIN NUMBER: Agents have to enter a PIN to log into the group.
GBUSY NEXT: If all agents are busy go directly to next destination.
You have now completed the UCD programming.

Overview
The MGI VoIP (Media Gateway Interface) series card is a standard and proprietary
based Voice over Internet Protocol option card that provides toll quality voice and
seamless integration with the OfficeServ 7100 systems via an IP network. The
OfficeServ 7100 can support the MGI-16 card. However, the OfficeServ 7100’s MP-10
processor card comes with 8 MGI channels intergrated on board. These channels can
be activated by the appropriate license key. The MGI also supports Samsung’s
proprietary ITP 5100 series IP keyphone, Wireless Handset, and Softphone. MGI
converts voice and signaling into IP packets, which can be transmitted over any TCP/IP
network so that voice looks like data. VoIP provides the solution for desktop
accessibility in the enterprise business environment. The easy addition of MGI boards
in the OfficeServ 7100 systems requires no integration into a server or desktop
personal computer. VoIP calls can be established from desktop telephone instruments
without complex integration of software or hardware. VoIP eliminates the cost of
maintaining separate networks for voice communications in the Intranet environment.

VoIP Overview
VoIP is transported by the OfficeServ 7100 MGI utilizing the standards based Internet
Protocol. This standard addresses the means of transferring voice, data, and images
through IP (Internet Protocol) networks. IP is the accepted protocol standard for
transporting data. With VoIP certain compression standards have also been adopted to
represent each second of voice with an amount of bandwidth. The OfficeServ 7100 MGI
can utilize G.711, G.729A, G729 or G.723 standards voice compression codec's (card
dependant). This allows for a selectable 64kbps, 8Kbps or 6.3Kbps bandwidth use
when preparing voice compression for IP transport on a particular network.
Compression is used to reduce the digitized voice into a smaller bandwidth that can be
carried in smaller packets. The MGI can determine the compression method for each
individual call setup. There is also a certain amount of frame/packet overhead in each
compression channel. 64Kbps of bandwidth can support 4~5 calls simultaneously.
This can vary depending on efficiency features like codec selection, Silence
Suppression and Multiframe counts. Unlike switched networks, VoIP connections use
the packet switching method and consist of a sequence of numbered of data packets.
Since voice conversation is usually considered “real time” these packets need to be
delivered in a consistent manner with minimal delay.
In any IP network environment, packet transfers are subject to delays and/or loss. If
these delays are great, the voice quality will deteriorate severely. The Ethernet data
traffic and network topology should be a consideration when applying VoIP transport.
Network congestion does affect call quality in any VoIP application.
ITP 5100 Series Keyphone Overview
The Samsung ITP 5100 series IP keyphones provide full iDCS keyphone functionality
locally or remotely on an IP network. The unique ITP keyphone instruments
communicate with the OfficeServ 7100 system in a proprietary IP message format to
emulate full keyphone functionality. Working in conjunction with the MP10/MP10a and
the MGI, the ITP keyphone can access all station features and trunk facilities on the
OfficeServ 7100 system. The ITP keyphone can function on private networks (Intranet)
or public IP networks (Internet). ITP keyphones support DHCP services and can also
function behind NAT (Network Address Translation) routers. All of the ITP models
support PoE (Power Over Ethernet, IEEE 802.3af). This means that they can be
powered by any PoE LAN switch instead of the AC adapter. Of course they can still be
powered by the AC adapter connection to an AC outlet. There are three types of ITP
5100 series keyphones:

NOTE:
The OfficeServ 7100 supports two forms of MGI’s:
1. On-board 8-channel MGI that is integrated on the MP-10 card. This form of the
MGI shares the same IP configuration and physical LAN connection as the MP-
10. The on-board channels are activated by license key.
2. MGI-16 card can be installed in either of the two universal slots. This card offers
16 channels and must be assigned its own unique IP configuration and has its
own LAN connection.
MGI Hardware Overview
The MGI (Media Gateway Interface) card supports a diverse range of features and
applications. The selectable features are H.323 VoIP trunking, SIP VoIP trunking,
OfficeServ 7100 System Networking via IP and the Samsung ITP 5100 series
keyphones. MGI cards support these features on a per port basis. Each MGI card has
an embedded RJ 45 10/100 BaseT Ethernet female connector on the face of each card
which allows a standard RJ45 UTP data cable connection for IP network connections.
LEDs on the front of the card provide operational status. The MGI cards automatically
detect 100BaseT Ethernet networks. There are no selectable options on the MGI cards.
The on-board MGI of the 7100 shares the MP-10’s RJ-45 connector.
The on board MGI and the MGI-16 support the following services and features:
•IP Phones

MGI Card Installation
If you are using the on-board MGI channels, then log into system programming and
enter MMC 841. Select the “MP MGI/VM KEY” option and enter the appropriate license
key to activate the MGI channels.
The MGI-16 card can mount in any OfficeServ 7100 universal card slot. Add as many as
needed. You are only limited by the number of available slots.
There is a processor on the MGI-16 cards so it is not recommended to insert this card
with system power on. Refer to the OfficeServ 7100 Installation manual for further
details on MGI card installation. The MGI-16 card does not require a license key to be
activated.
Card Insertion
Power OFF the OfficeServ 7100 system. Insert the required quantity of MGI cards into
the appropriate card slots. Push firmly in the middle of both card ejectors on each card
to ensure that it is fully inserted into the backplane connector. Connect IP network
cable(s). Power ON the OfficeServ 7400 system.
MGI IP Network Connection Cable
The cable needed to connect the MGI-16 to an IP network is a standard “straight” 8
conductor data cable. This cable is sometimes referred to as a LAN UTP Category 5, 4
pair RJ45 male to male data patch cable. Connection to the network can be via a patch
panel or data hub type device. The data patch cable is not provided with the MGI card
and must be purchased separately though a data equipment supplier.
NOTE: The Ethernet network cables on the MGI-16 and MP10/MP10a cards MUST be
connected to the data network upon power up to detect the Ethernet connection. The
MGI or MP10/MP10a cards CAN be connected after power up but must be reset to
detect the network connection.
If you are using the on-board MGI channels, then you only need to connect one LAN
cable to the MP-10 LAN port.
MGI Operation Overview
The MGI cards have the voice CODEC’s for VoIP and an RJ45 10/100 10BaseT
connector for the network connection(s). The MGI handles the voice to data and data
to voice conversion while the MP10/MP10a handles call signaling and setup/tear down,
CODEC selection, availability, CODEC usage type etc. The MP10/MP10a also has an
RJ45 10/100 BaseT connector. BOTH the MGI and MP10/MP10a cards must be
connected to the same network together. This is required to reduce delay of
information if traversing routers and other data network equipment. Of course if you are
using the on-board MGI channels, the MP10/MP10a and the on-board MGI share the

same IP address and LAN connection since the MP10/MP10a also performs the MGI
function.
Unique programming allows the access to the private Intranet and Public Internet
services simultaneously. This is accomplished via programming static IP addresses for
specific uses.
The MGI use is distributed via channels. Port reference is used to accommodate a
more static perception of the MGI channel identity. For simplicity the word port will be
used to reference MGI card channels.
The MGI can be used for several functions simultaneously or individually. Each MGI
port will auto negotiate the service of each port for the type of usage required. This
means that the same port can use SIP trunking for one call and H.323 for the next call
without any programming changes. With multiple MGI cards installed, service grading
of the MGI can be programmed so that specific MGI channels can be selected for
different uses. This grading is similar to standard trunk grading where the number of
users do not match the number of available lines. If a one to one ratio is required for
total non-blocking service this can be accomplished via programming and selection of
the number of simultaneous uses in proportion to the number of MGI ports.
MGI card(s) use of services can also be shared. MMC 615: MGI Group, allows the
segregation of services to specific cards. MMC 724: Dial Numbering Plan, allows
addressing of the default numbers and trunk assignments to customize the application.
MMC 831: MGI Parameters provides the MGI card(s) with IP address information. The
MGI Services will be explained in detail in the MGI Functional Overview section found
later on in this Application Section.
MGI Services:
-H.323 Trunking Gateway
-SIP Trunking Gateway
-ITP keyphone CODEC support
-VoIP Networking (SPNet)
MP10/MP10a
The MP10/MP10a provides a robust IP platform on the OfficeServ 7100. The
MP10/MP10a supports the default LAN connection via the RJ 45 10/100 BaseT port on
the face of the card. This connects to the same IP network that the MGI card(s) are
connected to. (ITP keyphones can be on the same or a different network). The
OfficeServ 7100 system IP address is registered on the MP10/MP10a card. All IP
connectivity is directed to the MP10/MP10a IP address. MMC 830: Ethernet
Parameters, provides the selections for the system MP10/MP10a IP address.

MGI Card Relationships
Theory of Operation
When an IP call is directed to the OfficeServ 7100 system the MP10/MP10a performs
the call control and setup to the remote calling or called IP endpoint.
Once the MP10/MP10a negotiates the setup a determination is made if the IP call is
intended to be received by another IP device on the IP side or a TDM port on the circuit
switched side of the OfficeServ 7100. When the request is for a circuit switched side
connection, the MP10/MP10a controls the MGI and sets up a channel for the IP call to
use a codec on the MGI as a gateway to the circuit switched environment. The MGI
supports the voice codec to the trunks or stations inside the OfficeServ 7100 system.
All other controls are managed by the MP10/MP10a. i.e. Setup, teardown, LED status
updates in the case of the ITP series keyphones.
The same theory of operation applies on an incoming IP call. The called IP address is
the MP10/MP10a card. The MP10/MP10a informs the calling IP party that the voice
portion of the call will be managed by the MGI. See Figure 3.

ITP Keyphone and iDCS Keyphone Operation
The ITP 5100 series keyphones use the MGI as the voice gateway when connected to
the OfficeServ 7100 system stations or trunks. The MP10/MP10a is involved to provide
call setup and tear down, programmable button functions, displays and system feature
access.
ITP 5100 series keyphones provide Auto Codec Negotiation and follows the VoIP
codec settings of the MGI card(s) used. There can be more ITP keyphones than
