The Application View on the Trail Level
Back on the Working Path layer, a specific view of the Trail used for a TE can be achieved. This dialog can be called via the Working Path context menu > “Details”. See Main Application View/Edit.
Transport Entities:
In our example, the Application Trail View displays 3 Trails:
− P12 Trail,
− VC12 Trail,
− VC4 Trail.
Selected Transport Entity: Working Path
The screenshot below displays Working Path of the VC4 Trail using the construct as follows:
• For the Trail between NE 82 and NE 81:
− MC Matrix Connection between SAMO1 and LEDE1 of NE 82,
− LC Link Connection between NE 82 and NE 81 on VC4 layer,
− MC Matrix Connection between STM16 port and STM4 port of SAMO2 inside NE 81.
• For the Trail between NE 81 and NE 80:
− MC Matrix Connection between STM16 port and STM4 port of SAMO2 inside NE 81,
− LC Link Connection between NE 81 and NE 80 on VC4 layer,
− MC Matrix Connection between SAMO2 and LEDE1 of NE 80.
Application View on Trail Level
The provisioned circuit and details of Application View on Trail Level is shown in this diagram:
Details of Application View on Trail Level
Selected Transport Entity: Specific Data.
If the capacity of a used Trail (protected or unprotected) is of interest, this mask will help to focus on that information.
Capacity View: VC4 Trail Capacity
Based on our sample network:
− VC4 Trail Capacity of 63 x VC12 channel (1 x VC12 channel used, and 62 x VC12 Channels free).
− The VC12 Trail has 1 x P12 channel capacity (0 used and 1 free).
− The P12 Trail has 30 x T1 channel (1 used and 29 free).
Further details of Application Trail View is possible, e.g. on a specific section or link within the end-to-end connection. For example, to know about the remaining capacity of the STM4 Link between NE 82 and NE 81, right-click on the required LC and select the “Details” context menu as shown in Application View on Trail Level. This calls another Trail View of that particular section or link as shown in the screenshot below.

Capacity View: STM4 MS Trail Capacity
The following capacity information is available:
− STM4 MS Trail of 4 x J1 (VC4) channel (2 used, 2 are free).
− STM4 PMS Trail capacity of 1 x STM4 RS channel (1 used, 0 free).
− STM4 RS Trail capacity of 1 x STM4 MS (1 used, 0 free).
