Editing E1 Lines
The following sections describe how to change the default settings for E1 link
modules:
• Enabling or Disabling an E1 Line

Enabling or Disabling an E1 Line
By default, the BayStream software enables E1 line services when you add the
interface. You can disable or reenable this interface without moving physical
cabling.
Enabling or Disabling CRC Checking
Some E1 equipment expects a 4-byte Cyclic Redundancy Check (CRC) trailer at
the end of each frame. You can configure this interface to add the CRC trailer to
received frames by enabling it as a a CRC Line Type.
By default, the CRC trailer is not added to received E1 frames. Set CRC Checking
to E1CRC4 if the E1 equipment expects a 4-byte CRC trailer at the end of each
frame.
