the guidelines in the next section,

Guidelines for Digital Extension Jacks

Although only one logical ID is assigned to each digital extension jack, the system
automatically assigns two extension numbers:
The first extension number shown on Form 2a is assigned to an MLX
telephone connected to the extension jack.
The second extension number assigned to each jack is reserved for an
adjunct, such as an ISDN terminal adapter data terminal or desktop video
endpoint, connected to the MLX telephone.
If a personal or group video system is connected to the MLX port,
extension numbers are assigned to the video system for use in 2B Data
connections.
