FEATURES
§ Operates as M13 or E13 multiplexer or as
standalone T3 or E3 framer
§ Flexible multiplexer can be programmed for
multiple configurations including:
− M13 multiplexing (28 T1 lines into a T3 data
stream)
− E13 multiplexing (16 E1 lines into an E3 data
stream)
− E1 to T3 multiplexing (21 E1 lines into a T3
data stream)
§ Two T1/E1 drop and insert ports
§ Supports T3 C-bit parity mode
