DTE Interface
ASMi-52 supports the following DTE interfaces:
• X.21
• V.35
• RS-530
• E1, as per G.704
• T1
• Ethernet/Fast Ethernet bridge with VLAN support (combined with management
LAN port)
• IR-IP (IP router).
When ASMi-52 is ordered only with the 10/100BaseT port, it can be used to
transfer user and management data.
An unbalanced E1 interface is provided via an adapter cable (CBL-RJ-45/2BNC/E1).
The impedance conversion (120
Ω to 75 Ω ) is performed by ASMi-52 automatically
when the adapter cable connection is detected.
ASMi-52 supports multiple data rates between the range of 64 kbps and
4608 kbps. The data rate depends on the following factors:
• Unit rate mode (regular or low speed)
• Line interface type (2-wire or 4-wire)
• DTE interface type of the local and remote units (serial or E1/T1)
• Clock mode (internal or external)
• Single or multiplexed.
Table 1-2 and Table 1-3 detail the ASMi-52 data rates with the possible
combinations of rate mode types, line/DTE interface types, and clock modes.
