Two Vertical Ring

In an MDF (Main Distribution Frame) system, Two Vertical Ring refers to a setup with two vertical incoming line groups, allowing more external trunk lines or larger capacity telephone line distribution.

It is typically used when the system requires higher line capacity, such as in medium to large offices, buildings, and PBX installations.

Function:

• Brings in two sets of main external/trunk lines
• Works together with L Frame to mount Krone/LSA IDC punch-down blocks for line distribution
