5.9 CE-100T-8 Card
• Low order (LO) VCAT VC-3 circuit sizes of up to three members: VC-3-1v, VC-3-2v, or VC-3-3v
• Low order (LO) VCAT VC-12 circuit sizes of up to 63 members: VC-12-Nv (where N=1 to 63)
VC-3 VCAT circuits map administrative unit 4 (AU-4), and VC-12 VCAT circuits map tributary unit 12
(TU-12).
In addition, the CE-100T-8 card supports Generic Framing Procedure (GFP-F) and point-to-point
protocol/high-level data link control (PPP/HDLC) framing protocols. It also supports the link capacity
adjustment scheme (LCAS), which allows dynamic reconfiguration of the VC groups.
The CE-100T8 card also supports the link capacity adjustment scheme (LCAS), which allows hitless
dynamic adjustment of SONET link bandwidth. The CE-100T-8 card’s LCAS is hardware-based, but the
CE-100T-8 also supports SW-LCAS. This makes it compatible with the ONS 15454 SDH ML-Series
card, which supports only SW-LCAS and does not support the standard hardware-based LCAS.
SW-LCAS is supported when a circuit from the CE-100T-8 terminates on the ONS 15454 SDH
ML-Series card.
Figure 5-8 shows the CE-100T-8 card faceplate and block diagram.
