DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Features and technical reference 1487 Single-Digit Dialing and Mixed Station Numbering 20 nTransfer Observers cannot initiate a transfer while observing. If a user transfers a call, the observer is placed in wait state. The observer is bridged onto the call when the transfer is complete. Related topics Refer to ‘‘ Observing calls’’ on page 387 to administer service observing. Single-Digit Dialing and Mixed Station Numbering Single-Digit Dialing and Mixed Station Numbering allows easy guest access to internal hotel/motel services and provides the capability to associate room numbers with guest-room telephones. Detailed description You must create a dial plan for hotel/motel services and room numbers. Some suggestions follow. Refer to ‘‘ Dial Plan Record’’ on page 593 for more information. nAssign a single-digit extension to internal hotel/motel services such as room service. Assign single-digit extensions to individual-telephones or to a group of telephones (for example, to service the front desk). nAssign a prefixed extension to guest rooms. A prefixed extension is made up of a prefix and an extension up to five digits. The prefix identifies the call type. The switch collects dialed digits, removes the prefix digit, and uses the extension for further processing. nMixed station numbering extensions can have from one to five digits and can begin with any digit from 0 to 9. The first digit, in combination with the number of digits dialed, defines the call type. To differentiate between two numbers with the same leading digit but different lengths, the system monitors the interval after a digit is dialed and before the next digit is dialed. If the interval extends past the administered interdigit timeout, the system assumes that dialing is complete and calculates the number of digits dialed up to that point.

DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Features and technical reference 1490 Single-Digit Dialing and Mixed Station Numbering 20 When using prefixed extension numbers, it is not necessary to include an entry for the real extension number in the dial plan. The server is able to complete a call using the prefixed extension number. When dialing 7345 (where 7 is the prefix), the communications server will ring extension 345. When using a dial plan like the one above, which includes both prefixed and non-prefixed extensions, dialing 567 instead of 4567 will ring an administrative extension instead of a room. The dialing delays, which may not be perceived by hotel guests, will occur when dialing 6 and 7. The server must wait for the 3- to 9-second interdigit timeout to expire before the call will be sent. The user can preempt the timer by pressing the # key after the number has been dialed. NOTE: When using prefixed extensions, the extension that shows up on a display phone does not show the prefix. The prefix will not show up on CDR reports. If extension number 3315 is prefixed with a 6 and the dial plan shows 3xxx for extensions, it is possible to dial either 3315 or 63315 to reach extension 3315. If the dial plan was changed to remove the entry for extensions in the 3xxx block, then 3315 could be reached only by dialing 63315. Considerations nMixed Station Numbering allows guest room numbers and room extensions to be the same. nYou cannot assign prefixed extensions longer than five digits (including prefix) to intercom lists. nA trunk access code (TAC) and an extension can share a first digit only if the extension is shorter than the TAC. nAlthough extensions with the same first digit can have different lengths, data-channel extensions must have the maximum number of digits to avoid timeout problems for data calls that the switch automatically sets up, for example, via the Call Detail Recording (CDR) link. nAn extension and a FAC can share the same first digit only if the extension is longer as long as they are not used for Automatic Alternate Routing/Automatic Route Selection (AAR/ARS) faxes. These extensions work only within the switch; they do not work as remote uniform dialing plan (UDP) extensions. nYou should administer the Short Interdigit Timeout on the Feature-Related System Parameters screen to ensure that the delay between the end of dialing and call completion is not too long.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Features and technical reference 1491 Station Hunting 20 Interactions nAttendant Display and Telephone Display Prefixed extensions display without the prefix. The return call button causes the prefix to dial, even though it does not display. nProperty Management System (PMS) Remove prefixes before messages containing the extension are sent to the PMS. Five-digit extensions do not exchange with PMS until modifications are made to the PMS interface. nUniform Dial Plan The following limitations apply to a distributed communications system (DCS) environment: — Extensions that differ in length from the UDP do not distribute to other switches. — If the first two digits of an extension correspond to the floor number, floors cannot be serviced by more than one switch. Station Hunting Station Hunting routes calls made to a busy station down a chain of stations until one is found that is not active. Detailed description To use Station Hunting, you create a station hunting chain that governs the order in which a call routes from one station to the next when the called station is busy. Each station in the chain links to only one subsequent station. However, any number of stations may link to one station. The system updates the calling party’s display with “h” when the system begins checking the station-hunting chain. Likewise, the system updates the display of the station that is hunted-to (the station that takes the call) with an “h.”
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Features and technical reference 1492 Station Hunting 20 Calls route through the chain as follows. There is no limit to the number of extensions that can be in a station-hunting chain. Station Hunting examples In this example (Ta b l e 5 6 ), extension 2 is the called extension. Because extension 2 is busy, the system follows the station-hunting chain to find an idle extension. The system cannot find an idle extension so it returns busy tone to the caller. Note that the chain terminates with extension 5. This means that the system cannot route the call to extension 1 even though it is an idle extension in the chain. Table 55. Station Hunting Characteristics Condition Response Encounters an idle extension Rings extension Encounters an active extension Routes to next extension in chain Encounters an extension with a blank hunt-to station fieldReturns busy tone if no station was idle Encounters any station a second time Returns busy tone Has checked 30 stations in the chain, without finding an idle oneReturns busy tone Table 56.

DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Features and technical reference 1493 Station Hunting 20 In this example (Ta b l e 5 7), extension 2 is the called extension. Because extension 2 is busy, the system follows the station-hunting chain to find an idle extension. The call is answered at extension 1. In this example (Ta b l e 5 8), extension 2 is the called extension. Because extension 2 is busy, the system follows the station-hunting chain to find an idle extension. The system encounters extension 3 a second time without finding an idle station. The system stops checking the station-hunting chain and returns busy tone to the caller. Notice that both extensions 5 and 2 link to extension 3. Station hunting options You can administer the system to perform station hunting prior to sending calls to coverage. The Station Hunt Before Coverage option on the System-Parameters Call Coverage/Call Forwarding screen provides that when a call is made to a busy station, the switch checks to see if there is a hunt-to station assigned to the busy station. If there is, the switch tries to connect to the hunt-to station before going to Table 57.

DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Features and technical reference 1494 Station Hunting 20 coverage. If the hunt-to station is also busy, the switch continues hunting down the hunt-to chain. If all stations in the hunt-to chain are busy, the call goes to the dialed station’s coverage. Administration commands When you remove a station, the system attempts to maintain a station-hunting chain. Consider the following examples: nStation 1 links to 2 and 2 links to 3. If you remove station 2, the system links 1 to 3. nStation 1 links to 2. Station 2 does not link to another extension. If you remove station 2, 1 no longer links to another extension. When you duplicate a station, the extension in the hunt-to station field is not copied into the duplicated station. When you execute “ list usage extension xxxxx,” the system displays all stations that contain the station’s extension as their hunt-to station. Interactions Remember that the system checks the station-hunting chain only for idle and available extensions. nAdjunct Switch Applications Interface The system attempts Station Hunting when ASAI routes to an extension with a hunt-to station. nAutomatic Call Distribution An agent extension can be part of a station-hunting chain. The system hunts the agent’s chain only when the call is made directly to the agent’s extension. Calls distributed through hunt groups to an ACD agent do not hunt the agent’s station-hunting chain. Calls made to an extension for logical agents do not hunt the agent’s station-hunting chain. nAutomatic Callback The system does not hunt the chain of the called extension when the call is a callback-return call. nBridged Appearance The system hunts the extension’s station-hunting chain if the principal station has no call appearance at which the call can terminate, even though it may have available bridged appearances on other stations.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Features and technical reference 1495 Station Hunting 20 nBusy Verification The system does not attempt Station Hunting for busy-verify calls. nCall Coverage Call Coverage has precedence over Station Hunting. Station Hunting is applied to the final coverage point following the final coverage point’s hunt-to chain when the following conditions occur: — The Call Coverage screen’s Hunt After Coverage field is y. — The last coverage point is unavailable (busy or no answer). — The last coverage point is a station with an assigned hunt-to station. — No one in the coverage path answered the call. Coverage — Don’t Answer will cover the call after hunt if the call can terminate, but no one answers. If Station Hunt Before Coverage is active, a call to a busy station tries to terminate to the hunt-to phone before going to coverage. If the call does go to coverage, it is the coverage of the dialed extension (unless the phone is an XDID, and then the call goes to the coverage of the non-XDID phone found in the XDID’s hunt-to field). nCall Detail Recording CDR records the called extension, not the answering extension. nCall Forwarding Call Forwarding has precedence over Station Hunting. If an idle station has Call Forwarding active, the system forwards the call. If a busy station has Call Forwarding active, a call to the station forwards. If the forwarded-to station is busy, the call follows that forwarded-to station’s hunting chain. If the system finds Call Forwarding active at one of the stations in a station-hunting chain, it considers the station busy and bypasses it. The call goes to the next station in the chain. nCall Park The system does not attempt Station Hunting on callpark-return calls. nCall Pickup Call Pickup functions the same for calls terminating at a point in a station-hunting chain as it does for a regular calls.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Features and technical reference 1496 Station Hunting 20 nCall Vectoring You cannot assign a Vector Directory Number as a hunt-to station. If a route-to command’s with cov y directs a call to a busy station, the call follows the station’s hunt-to chain and not its coverage path. Refer to DEFINITY ECS Call Vectoring/EAS Guide or DEFINITY BCS and Guestworks Call Vectoring Guide for more information. nCall Waiting/Attendant Call Waiting Station Hunting has precedence over Call Waiting. If a called extension has Call Waiting active, and the extension is already busy on a call, the system hunts the station-hunting chain. If the system cannot terminate the call to a member of the chain, then the call waits at the called extension. If the system finds Call Waiting active at an extension in a station-hunting chain, it considers the extension busy and bypasses it. nClass of Restriction The system checks the COR of the called extension; it does not check the COR of the hunt-to stations in the chain. nDistributed Communications System Station Hunting is not a DCS feature. All members of a station-hunting chain must be on the same switch. nDo Not Disturb When a phone has Do Not Disturb activated, a call to that phone goes to intercept treatment and not to station hunting. nExtension Number Portability You cannot assign a remote ENP extension as a hunt-to station. nHunting/Hunting Group You cannot assign a direct departmental calling or Uniform Call Distribution extension as a hunt-to station. nIntercom Call The system denies Station Hunting for intercom calls to a busy extension. nLeave Word Calling If a caller initiates Leave Word Calling (LWC), the LWC message is left at the called extension even if the system uses Station Hunting in an attempt to complete the call. nMultimedia Calls to multimedia endpoints must convert to voice before station hunting.
