Configuring E1 Interface
IPmux-8/16 supports up to 8 or 16 E1 links. Each E1 interface must be configured
individually.
Path: Main > Configuration > Physical Layer Configuration > Slot # 3/4 >
Channel #1–4 or Channel #1–8.

To configure E1 interface:
1. Follow the path above to access the E1 Physical Layer Configuration menu
(
Figure 4-9).
2. From the E1 Physical Layer Configuration menu, configure the following:
 Channel Status
 Enable (E1 link is enabled)
 Disable (E1 link is disabled)
 Transmit Clock Source
 Adaptive (Adaptive clock regeneration)
 Loopback (E1 recovered Rx clock is used as the Tx clock)
 Internal (Tx clock is received from an internal oscillator)
 External (Tx clock is received from the external clock input)
 Loopback State (Controls activation of diagnostic loopbacks, see Diagnostic
Loopbacks in Chapter 6 for detailed loopback function explanation)
 Internal (Internal loopback is activated)
 External (External loopback is activated)
 Disable (All loopbacks are deactivated)
 Rx sensitivity (Maximum attenuation of the receive signal that can be
compensated for by the interface receive path)
 -10 dB
 -32 dB
 Line Type (E1 framing mode)
 Unframed (Framing is not used)
 CRC4 Enable (G.704 framing, CRC-4 function enabled)
 Framed G.704 CRC4 (G.704 framing, CRC-4 function disabled)
The following parameters are masked when the line type is set to unframed:
• UpLink Fail Alarm Behavior
• Idle Code
• Signaling Mode
• Cond. Data Pattern
• Cond. CAS (ABCD) Pattern.
