13.1.2 Paralleled Telephone
13.1.2 Paralleled Telephone
Description
By connecting telephones in parallel, you can increase the number of telephones connected to the PBX without adding additional extension cards.
Both wired and wireless telephones can be connected in parallel. Single line telephones (SLTs), analog proprietary telephones (APTs), and digital proprietary telephones (DPTs) can be connected to other telephones or connectors, allowing up to three telephones to be connected to the PBX through just one extension port. Additionally, portable stations (PSs) can be linked to other telephones wirelessly and used as "paired" extensions.
The different type of parallel connections are described below.
Features
Parallel Mode
EXtra Device Port (XDP) Mode
Digital XDP
Descriptions
Allows an SLT to be connected to an APT or DPT which is connected to a Super Hybrid port of the PBX. When parallel mode is enabled, the two telephones function as follows:
•Both share the extension number of the telephone connected directly to the PBX (main telephone).
•Either telephone can make or answer a call.
Allows an SLT to be connected to a DPT which is connected to a Super Hybrid port of the PBX. Unlike parallel mode, XDP mode allows each telephone to act as an independent extension with its own extension number. (→ 5.1.7 Extension Port Configuration)
Allows a DPT to be connected to another DPT which is connected to a DPT port or a Super Hybrid port of the PBX. The DPT that is connected directly to the PBX is called the "master DPT", and the DPT connected to the master DPT is called the "slave DPT".
Similar to XDP mode, each DPT acts as a independent extension with its own extension number.
If a master DPT is connected to the PBX by a Super Hybrid port (not a DPT port), a third telephone (SLT) can also be in parallel or XDP mode with the master DPT.
Digital XDP connection allows the number of DPTs that the PBX supports to increase.
