Configuring MCE1 and MCT1 Interfaces
114078 Rev. A 6-7
Enabling or Disabling the International Bit
By default, the MCE1 interface does not use the international bit in E1 frames.
You can enable use of the International Bit for this MCE1 interface.
Setting the Line Impedance (ASN MCE1 only)
The line impedance for the ASN MCE1 net module is 120 Ohm by default. For
the ASN MCE1 net module only, you can change the line impedance to 75 Ohm
for an interface.
Customizing MCT1 Port Details
You set values for configurable MCT1 port service details and enable or disable
the MCT1 port at the MCT1 Edit Port Parameters window
(Figure 6-3). To
customize MCT1 port parameters, select new values for the parameters you want
to edit. See the following sections:
• Enabling or Disabling the MCT1 Port
• Setting the MCT1 Line Type
• Setting the Line Coding Method
• Setting the Signal Level
• Setting the Alarm Threshold Time
• Setting the Alarm Threshold Clear Time
• Setting the FDL Mode for ESF Line Types
• Setting the Remote FDL HDLC Address Mode
• Enabling or Disabling Loopback Requests
• Setting the Loopback Configuration
• Setting the Source of Send Performance Messages (QMCT1)
• Setting the Source of Accept Performance Messages (QMCT1)
• Setting the Primary Clock Source (QMCT1)
• Setting the Secondary Clock Source (QMCT1)
