Release 25 Summary of Features
Capacity Expansion
Call Processor PII – Increases the Option 81C busy hour call completion (BHCC) capacity significantly beyond target competition and
supports up to 1,200 complex Symposium Call Center Server (SCCS) agents (20+ skill sets). It allows for future Meridian*
and/or intensive Symposium* product enhancements that can utilize the inherent higher capacity potential of CP PII. This
additional real-time support also allows for considerable port expansion. It adopts an industry standard embedded compute
platform (Compact Peripheral Component Interconnect (cPCI) and Intel PII processor).
Benefits: Employing off-the-shelf components provides a migration path to an open data model. Large installed base customers can
now continue with one platform as they experience growth both from a port capacity perspective as well as additional applications.
Fiber Network Fabric (FNF) – Provides increased network capacity with the addition of three network groups for a total of eight. Now
the Option 81 and Option 81C can experience growth to 16,000 ports. A 60% expansion. There is also a 60% increase in
trunk capacity. The fiber rings that carry the traffic for all eight network groups are redundant. Each ring addresses all eight
network groups.
Benefits: The additional capacity can now address larger Call Centers and tandem switches. It also eliminates contention for internetwork junctors while at the same time providing an additional level of reliability. Large installed base customers can now continue
with one platform as they experience growth both from a port capacity perspective as well as additional applications because it is fully
compatible with current network, CPU and applications equipment as well as existing inter-group architecture.
D-Channel Expansion – The D-Channel Expansion feature provides increased network capacity and increased digital trunking capabilities. It increases the total number of logical D-Channel (DCH) applications in the system from 64 to 255 for Options 51C –
81C and increases the number of physical I/O addresses allowable for D-Channel only applications to 16 per network group.
The feature allows more physical I/O addresses to be used for other I/O devices e.g. QPC841, since the DDCH and MSDL
(with DCH applications only) can share the same addresses as long as they reside in separate network groups.
Benefits: Allow the customer to expand their network and increase the capacity of PRI trunks into the call center.

X11 Feature Summary 13
X11 Release 20 (12/94)
X11 Release 20, introduced in the first quarter of 1995, combines what was two separate streams of software, the North American
and International streams, to provide additional features and functionality into the North American market.
General Business Features
Call Forward & Busy Status provides a secretary with the status of monitored sets (Busy and/or Forwarded). The feature key can
also be used to forward or dial a monitored set.
Call Forward / Hunt Override via FFC, when used before dialing a number, will override Call Forward All Calls, Call Forward
No Answer and Hunting.
Dial Access to Group Call allows a person to access the Group Call feature from any phone by dialing a flexible feature code.
Multi-Party Operations has several sub-features. Call Join allows two independent calls that are active on one telephone to be joined into
a conference. Three Party Service allows the user of an analog telephone to toggle between two separate parties before conferencing them together. Recovery of mis-operation of Call Transfer will prevent callers from being disconnected if a
transfer attempt is made to a vacant number or to a busy station.
Make Set Busy/Voice Call Override can be used to place a call to a telephone that has the Make Set Busy feature activated.
Priority Override allows someone to break into a busy call of a station that has a lower priority.
Restricted Call Transfer denies any attempt to transfer a call. This differs from Transfer Denied class of service, which will present
a call to the attendant if a transfer is attempted.
Ring Again on No Answer allows the Ring Again feature to be activated against a station that does not answer (as opposed to only a busy
station). When the called party next uses their telephone and disconnects, a notification will be provided to the original calling
party allowing one button redial to the desired station.
Station Camp-on provides the capability to transfer an external call to a busy station where it will be “camped on”. The busy station
will receive a camp on tone and will be presented with the call when they hang up.
Speed Call on Private Lines extends the speed call capability to calls made on a private line.
Attendant Features
Attendant Break-in simplifies the process of delivering an emergency call to a busy station.
Enhanced Night Service offers alternate night service options for weekend and holiday schedules.
Recall To Same Attendant simply delivers a recall (i.e., a call that has returned to an attendant because of no answer) to the
attendant that last extended the call. If busy, the call can overflow to another attendant or queue to the last attendant.
Recovery of Misoperation of the Attendant Console prevents the attendant from dropping a call by transferring to a vacant
number, busy station, or a number without enough digits.
Trunk Hook Flash Enhancement allows the attendant console to be configured with Trunk Hook Flash capabilities used
to access CENTREX features.
X11 Feature Summary 14
Networking Features
Network Attendant Service provides the ability to have attendants distributed throughout a network sharing the workload. Calls
can be re-routed to an alternate attendant (at a remote location) based on a variety of reasons (e.g., Overflow, Time of
Day, Night Service, etc.)
Attendant and Network Wide Remote Call Forward extends the capability to remotely forward a telephone over the network
and provides the attendant the ability to verify forwarding status and to change the forwarding of a telephone.
Network Wide Listed Directory Numbers (LDN) Provides two additional LDN keys to be programmed on a console. When
used with Network Attendant Service, it will allow LDN keys to be configured for the LDN of a remote location.
System Features
Autodial Tandem Transfer permits the autodial feature to be used in conjunction with Trunk Hook Flash when accessing
CENTREX features.
Call Forward Save on Dump/Sysload saves the Call Forward status of telephones after a Sysload (e.g., when upgrading software).
The system restores the Forward to the status as of the Data Dump (or data save).
Dialed Number Identification Services (DNIS) Length Flexibility allows the DNIS number to be flexible from 1 to 7 digits
instead of 3 or 4 digits.
Malicious Call Trace DN/TN Print provides more information about a Malicious Call (i.e., whether the call was internal or
external and the CLID if offered).
Enhanced Malicious Call Trace allows a recording device to be conferenced with a Malicious Call. Also provides the ability
to configure a maintenance terminal to output only Malicious Call Trace information (i.e., for a security office).
Flexible Feature Code Enhancements provides access to Autodial, Call Waiting, Make Set Busy, and Multiple Automatic
Wake Up using Flexible Feature Codes.
Flexible Numbering Plan supports a network with Directory Numbers and Location Codes of varying lengths.
Also supports Vacant Number Routing.
Global Call Detail Recording (CDR) Record provides the option of providing a new formatted CDR output,
information on time to answer, information on abandoned calls, and a new record type “D” for station monitoring.
Phantom TN Operation provides the ability to configure a TN with no associated hardware. A useful application is “Virtual Office” or
“Hoteling” office space if employees spend most of the time out of the office.
Recall After Parking allows calls to either recall to the station that parked the call or to the attendant.
Scheduled Access Restrictions allows calling restrictions to be placed on stations within a group based on time of day and days of week.
Station Activity Record provides a way to monitor internal and external activity on a single telephone without turning on
CDR records for the whole system.
Trunk Barring restricts certain defined trunk-to-trunk connections for the purposes of conferencing or transferring.
