Feature	Description
Calling Line Identity Presentation (CLIP) £2 per month	This service allows the called customer to receive the caller's line identity (telephone number) before answering the call. The called party will only receive this information if the calling party has agreed to send their number (CLI).
Calling Line Identity Restriction (CLIR) £2 per month	Customers can request that their identities (telephone numbers) are not released at any time. This service is available free of charge when ordered with the ISDN 30 line.
Connected Line Identity Presentation (COLP) £2 per month	Allows you to confirm that the number you have dialled is the number you are connected to and that you have not been forwarded to another location. Activation/deactivation of this facility is not available on a per call basis.

Call Forwarding of Voice and Data Calls (Admin set up only) Unconditional On All Calls £2 per month	All calls incoming to the diverting group of lines are immediately diverted to the directory number that was nominated to receive the diverted calls
Call Forwarding of Voice and Data Calls (Admin set up only) On Busy £2 per month	Diversion/Forwarding on Busy is provided so that customers have the opportunity to ensure that any overflow traffic at one location can be answered elsewhere. ISDN 30 (DASS2) will divert calls when all channels are busy. ISDN 30e will forward calls when either all channels are busy or when a specific DDI extension is signalled to be busy by the iSPBX.
Call Forwarding of Voice and Data Calls (Admin set up only) On No Reply £2 per month	Provision of Diversion/Forwarding on Ring Tone or No Reply means that calls will be diverted to a pre-arranged telephone number if the call isn't answered within approximately 20 seconds.
Customer controlled call forwarding of Voice and Data Calls Unconditional On All Calls £2 per month	This is the Call Forwarding option that allows you to control the Call Forwarding service from your PBX / equipment. You can choose to forward all calls, on busy, or on no reply. The forwarded part of the call will be charged to whoever invokes the Call Forwarding facility. You are advised to check that your equipment supports the relevant Call Forwarding service offered. Call Forwarding on ISDN 30e allows both voice and data calls to be forwarded.

Call Deflection (CD) £2 per month	Allows you to respond to an incoming voice or data call by deflecting the call to another number without answering it. The "forwarded to" number must be able to accept the calls, for voice calls any normal number that accepts incoming calls (such as a mobile phone or analogue exchange line) can take the call. The ability to use this service is dependent upon your equipment. You can control the criteria that determines which calls are forwarded, for example on the basis of who the call is from, who it is made to, the call type etc.
20 Octet Sub Addressing £2 per month	Sub Addressing (also known as Network Address Extension) For ISDN 30 this would apply to equipment that supplies ISDN 2e ports to the user. With ISDN 30e, up to 20 Octets can be sent to other ISDN 30e or ISDN 2e lines. This allows the caller to select a destination, device or end-point beyond that indicated by the called national number (for example a process in a host computer or a device connected to a LAN, or individual devices connected to an ISDN 2 port). Assuming your equipment supports this facility, the caller may send his calling sub address but the called party must have CLIP to receive this facility.
Caller Redirect £2 per month	Caller Redirect is a service provided at the End User's local exchange that informs incoming callers of the called party's new telephone number. When an End User ceases service and takes up service elsewhere, or has a line renumbered, Caller Redirect will refer callers to the new number (the caller is not charged for the call).
DDI £0.40 per number per month	Direct Dialling In combines the benefits of direct access to extension users without the need for individual exchange lines to be associated with each user or going via the operator. The principle by which DDI works is that typically the last six digits of the dialled number are forwarded to the iSPBX over a group of ISDN lines and are used for call routing. This enables a range of public exchange numbers to be allocated to the iSPBX, and for each extension user to have the equivalent of his or her own exchange line. Frequent callers can then call directly to the person they wish to contact. A number from within the DDI range can be allocated as the main number for calls to the iSPBX operator. This would be the Company's main published number for callers who do not know the relevant DDI number of the person or department they wish to contact.
Presentation Number £2 per month	Presentation Number is a service that allows users to specify a telephone number for the Calling Line Identity (CLI) on outgoing calls, which may be different to the main telephone number.
Anonymous Call Reject £20 per month	This can be used where the caller(s) are withholding their CLI. It will prevent most calls with CLI Withheld being made to the number selected. Users should be cautioned, however, that it is likely to stop other people they would be happy to speak to from phoning them (e.g. doctors, hospitals and numerous other large organisations). ACR will not reject International Calls.
Power Supply please call for pricing	The 2Mbit/s NTE fitted when copper cable is used does not require a power supply as power is line fed from the BT exchange over the copper cable. The 2Mbit/s NTE fitted when fibre optic cable is used does require a power supply.
Standby Power please call for pricing	If required, standby batteries can be supplied at a charge, giving up to five hours backup supply. Alternatively, power can be supplied from CPE equipment if it has standby power. This will give protection in the case of a power failure so that calls can be made, but only if the iSPBX has standby power as well. If no standby power is fitted and the power is switched off to the NTE, service will automatically be restored when the power comes back on.
