Serial DTE = V.35, X.21, RS-530.
The following are multiplexer conditions when working with the ASMi-52 unit:
• E1+Serial DTE can work as an ‘E1 port only’ or a serial DTE port only.
• E1+LAN can work as an ‘E1 port only’.
• LAN+Serial DTE can work as a ‘Serial DTE port only’.
• E1+Ethernet and Serial DTE+Ethernet can be configured as a single port only
(‘E1 only’ or ‘Serial DTE only’) while the Ethernet port operates as a
management port only.
ASMi-52 E1 or Serial DTE units with a LAN management port previously released
with software versions earlier than version 2.5 cannot operate as a multiplexer
unit (E1+LAN, Serial DTE+LAN) with version 2.5 and higher due to hardware
differences.
Timing
ASMi-52 supports three clock modes:
• Internal, derived from its internal oscillator (CO mode)
• External, supplied by the attached DTE
• Receive, recovered from the received line signal (CPE mode).
