SONET Port Encapsulation

The ML-Series supports three forms of SONET port encapsulation:

1. Cisco

HDLC

2. PPP/BCP
3. LEX

Cisco HDLC is standard on most Cisco data devices. It does not offer VLAN trunking support.
PPP/BCP is a popular standard linked to RFC 2878. It supports VLAN trunking via BCP. LEX is
a protocol used by the G-Series cards. This protocol supports VLAN trunking and is based on
PPP over HDLC.

This allows the ML-Series to connect to the OC-N ports of switches and routers supporting POS,
as well as the G-Series Ethernet cards on the Cisco ONS 15454 MSPP. All three formats
support bridging and routing, standard SONET payload scrambling, and HDLC frame check
sequence.
