| VCTRUNK Specifications |
Quantity:
- N1EFS4 has a VCTRUNK quantity of 12.
- The number of VCTRUNK for N2EFS4 and N3EFS4 is 24.
Configuration Features:
- After a VC channel of each level is used by one VCTRUNK binding, other VCTRUNKs can no longer be used.
- N2EFS4 and N3EFS4 slots with a bandwidth of 622M bit/s need to be bound to use VCTRUNK1 to VCTRUNK12.
- The same VCTRUNK can only bind one level of channel, and cannot bind both VC-12 and VC-3 channels.
- VCTRUNK1 to VCTRUNK12 can only bind low-order services of 1 to 4 VC-4 channels, and VCTRUNK13 to VCTRUNK24 can only bind low-order services of 5 to 8 VC-4 channels.
- Each VCTRUNK can bind up to 12 VC-3s or 63 VC-12s.
- The two VC-4s, 4 and 8, can be bound as both VC-3 and VC-12 channels, while the other VC-4s can only be bound as VC-3 channels.
