BT Item Code: 871126

Relate 2000
The BT Relate 2000 is a highly featured PSTN Videophone which can send a video image of the caller over the PSTN to another Videophone. The Relate 2000 is also compatible with audio only telephones. The Relate 2000 can be wall or table mounted and has the following facilities:

KEYPAD
Twelve alpha-numeric keys, (0 to 9, * and #), Seven function keys and eight video control keys. A shift key, used in conjunction with some of the keys, gives added facilities. In common with the Relate range, the dialling keys are lettered and numbered.

AUDIO FUNCTIONS
Tone caller
Incoming calls are signalled by a tone caller which has an adjustable volume control on the underside of the telephone with HI, LO and OFF settings. The tone and frequency can also be set through software control.

Secrecy
Pressing the SECRECY button will cut off sound transmission in audio mode, or sound and video transmission in video mode without affecting incoming speech or video. It can be used in handset or loudspeaking mode. Press Secrecy button again to reinstate transmission. An indicator will light when secrecy is in use. Secrecy is automatically switched off when a call is completed, but is not affected when switching between video and audio operation.

Pause
Allows a pause of 3.4 seconds, with a maximum of three pauses to be inserted in a stored number. This is required by some PABXS.

Memory Store
Up to 10 numbers of up to 20 digits long may be stored. These numbers and redial are stored in EEPROM and will be retained, without power source, for up to five years.

Memory recall
Operation of this key, followed by the memory number, will call the stored number.

Recall
Timed Break or Earth Loop Recall.

Redial
With the handset lifted, or in loudspeaking mode, pressing the REDIAL button will cause the last number dialled to be repeated.

Loudspeaking
Allows full handsfree operation. The indicator adjacent to the key will light when loudspeaking is in use.

Timer
This key, mounted under the hinged video unit, displays the time since handset lifted. Incoming and outgoing calls can be timed, in hours and minutes. If no call is in progress, the time displayed will be the last call made. The timer will only operate when connected to the mains power supply.

VIDEO FUNCTIONS
Colour Liquid Crystal Display.

The LCD is a 2.9" screen which displays the incoming video signal at a rate of 8 frames per second. If the picture is unclear due to line noise or other interference, the rate may be slowed to 3 - 4 frames per second.

Video On/Off
The call will be established as a voice call. To protect user privacy, video can only be switched on by mutual consent with both parties having agreed to a video connection and having compatible video telephones. The Video On/Off keys of each telephone must be pressed within five seconds of each other. Whilst the link is being made, the screen turns blue and displays "wait"; the line will also appear "dead". Further operation of the key, during video, will remove the video link and restore the call to audio only.

Contrast brightness and colour setting
These keys allow the user to adjust their display for optimum effect. Pressing brightness alters the brightness of local picture and contrast alters contrast of local picture. Colour control does not affect the local picture unless in self view. Colour of the received video signal is controlled by the distant end using shift contrast.

Self view
With a video call in progress, the left hand corner of the screen will display the transmitted picture ("picture in picture" facility). This can be removed by operation of the SELF-VIEW key. SHIFT/SELF-VIEW enables a full picture of the out-going signal to be seen, so that a check of what the distant end is receiving can be made.

Shift
Operation of the SHIFT key together with SELF-VIEW allows the user to see a mirror image on the screen. It is recommended that this is used before making a video call. The method by which a mirror image is obtained varies depending upon the mode of operation;

SHIFT/SELF VIEW with handset on hook or in video mode.
SELF VIEW only with handset off hook and no call or voice call only.
Freeze frame
Allows the user to freeze the display at any time during a video call. Further operation unfreezes the display. There is a short delay whilst the picture builds up. During this time WAIT is displayed.

Video refresh
During freeze frame, operation of VIDEO REFRESH will update the screen.

SIGNALLING
Controlled by a mode switch on the underside of the instrument.
P-E for pulse
T-E for earth loop
T-TB for timed break

ADDITIONAL INFORMATION

From August to December 1994, 7 corded telephones were launched as an overhaul to the existing Relate and Vanguard ranges.  The new range has been split, within the BT portfolio, to have residential products (new Relates) separate from business products (new Converses).

New Relate range is; Relate 80, Relate 180, Relate 250.
New Converse range is; Converse 100, Converse 180, Converse 250, Converse 400.

The new Relate range listed above will support Time Break Recall ONLY. The new Converse range will support both Earth Loop and Time Break Recall. Earth recall is mechanical and as such, cannot be programmed into digit strings, unlike TBR. This also makes the new Converse range Renown and 2+8 compatible.

 

ADDITIONAL INFORMATION FOR THE 100, 200, 300 and 400

Made by Northern Telecom Europe (NTE) Ltd

APPROVAL STATUS
Approved under Approval numbers:-

S/1000/3/M/502265 (Relate 100)
S/1000/3/M/502266 (Relate 200)
S/1000/3/M/502267 (Relate 300)
S/1000/3/M/502264 (Relate 400)

For use on DEL's and PBXs in categories 1,3,5,7,9 & 11.

The Relate range have a REN of 1 and are intended for use in normal Domestic/Residential locations or connected to any approved PBX.

Approximate overall dimensions - 150mm x 220mm x 95mm.
Weight - Relate 100, 712 grams, Relate 200, 794 grams, Relate 300 & 400, 834 grams.

Two 25mm x No. 8 pan-head wood screws and wall plugs are provided for wall mounted use via key-hole slots in the base of the instrument.

Three good quality AA size batteries are required for the Relate 300 and 400. However, the phone will operate perfectly satisfactorily without them. Batteries allow memory programming on hook and retain memories whilst the phone is unplugged.

Table mounted - the unit is supplied with a plinth to allow for an angled stance or without the plinth for a flat stance.

Wall mounted - the plinth is removed, turned, then refitted. This gives a good wall mounting angle. The handset and line cords may be routed through the alternative channels in the base as required and the line cord may be shortened. The handset retaining lug should be turned through 180 degrees to support the handset.

ROUTINE MAINTENANCE
The Relate 300 and 400 batteries should give 12 months service before replacement is indicated.

WARRANTY
BT's warranty from the manufacturer is for 24 months from date marking on the base (Week & Year forming first four digits of the serial number).

LINE TESTING
Idle - Normal capacitor loop, additionally these telephones draw on-hook current (typically 25 micro Amps) to maintain stored/last number memory. This may give apparent 'Low Loop' line test conditions.

Seized - Normal press button telephone loop. The electronic keypad and transmission circuitry may give 'high resistance' tele-loop line test conditions as with other press button telephones.

ADDITIONAL INFORMATION
Signalling details

MF signalling
- All models, continuous tone whilst button is pressed.

Timed break recall
- All models, approximately 90 ms.

Earth recall
- All models, approximately 800 ms.

PBX Interworking
Some facilities are not available when Relate range telephones are connected to a Renown or BT2+8.

Secrecy
The feature, when active, disables the handset whilst the LED is glowing. It also disables the base microphone in the Relate 400. On Relate 200 the LED will not illuminate when in Monitor mode.

Monitor Mode
The Relate 200 will not operate in Monitor Mode when first connected to line, or after a sustained line break (specified as 5 minutes but in practice 15 minutes or more). A handset lift, and replacement, is required to 'reset' the processor.

 

KNOWN ISSUES

RELATE 400: DELETING ENTRIES IN INTERNAL DIRECTORY
The Relate 400 user guide page 15 states that, when deleting an entry in the internal directory, the user can find the name to be deleted by either using the scan buttons or entering the initial letter of the name and THEN scan. The latter of these is incorrect; if the initial letter of the name is entered before pressing scan it locks the directory until the handset is replaced.

The full correct operation should be:
Lift handset (or press loudspeaking), Press store, Press directory button, Press scan, Initial letter (if required, followed by scan again), Press delete twice, Replace handset (or press loudspeaking again).

RELATE 100 & 200: RECALL PROBLEM ON MONARCH UPDATE (July 1994)
Briefly, the recall button was not recognised if held down, but a quick stab often succeeded. A serial number fix for this problem on the Relate 200 only is outlined below.

Modifications to the recall on Relate 200 telephones has been incorporated in units produced on or after week 19 of 1994 (i.e. serial numbers beginning 9419...).

RELATE 100 & 200: RECALL PROBLEM ON MONARCH (April 1994)
Recent modifications of Relate 100 & 200 to improve their compatibility with Renown and 2+8 systems have apparently caused a recall problem if the Relates are connected as Monarch extensions.

Users may experience difficulty in effecting recall with the modified instruments (although the 200 version does function correctly if used in monitor mode).

The problem may be perceived as ‘intermittent no recall’ as a long press of the recall will usually fail while a short stab often succeeds.

The fault, currently being investigated by the manufacturer, is apparent on Relate 100’s produced from week 37/93 onwards and on Relate 200’s produced on or after week 42/93.

RELATE 100: RINGING DIFFICULTY WHEN WALL-MOUNTED (April 1994)
A modified handset clip to improve handset capture is now in production.
