ONS 15454, ONS 15454 SDH, ONS 15310-CL, and ONS 15310-MA CE-Series Cards
Encapsulation and Framing
CE-100T-8 cards are available for the ONS 15454, ONS 15454 SDH, ONS 15310-CL, and ONS
15310-MA platforms. CE-1000-4 cards are available for the ONS 15454 and ONS 15454 SDH
platforms. They support HDLC Framing and GFP-F framing. Under the GFP-F or HDLC framing mode,
only LEX encapsulation is supported.

ONS 15310-CL and ONS 15310-MA ML-100T-8 Encapsulation and Framing
The ML-100T-8 card on the ONS 15310 supports HDLC framing and GFP-F framing. Under the HDLC
framing mode, LEX is supported. Under the GFP-F framing mode, LEX, Cisco HDLC, and PPP/BCP
encapsulation are supported. LEX encapsulation is also the encapsulation for Cisco proprietary RPR on
the ML-Series card. Cisco proprietary RPR requires LEX encapsulation in either framing mode.
ONS 15454 and ONS 15454 SDH ML-Series Protocol Encapsulation and Framing
The ML-Series card on the ONS 15454 and ONS 15454 SDH supports HDLC framing and GFP-F
framing. Under both the HDLC framing mode and the GFP-F framing mode, LEX, Cisco HDLC, and
PPP/BCP encapsulation is supported. LEX encapsulation is also the encapsulation for Cisco proprietary
RPR on the ML-Series card. Cisco proprietary RPR requires LEX encapsulation in either framing mode.
802.17b encapsulation is the set encapsulation in IEEE 802.17b compliant RPR, which is only supported
in GFP-F framing.
