D.4 Configuring IPmux-11 at the Physical Level
The TDM (E1 or T1) and Ethernet interfaces of IPmux-11 must be configured at
the physical level.
Configuring the E1 TDM Interface
The E1 and T1 interfaces of IPmux-11 is configured via the TDM Configuration
menu. IPmux-11 automatically detects whether the interface is E1 or T1, and
displays the appropriate menu.
To configure the E1 interface:
1. From the Configuration menu (Figure D-4), select Physical layer.
The Physical Layer menu appears (see Figure D-16).
2. From the Physical Layer menu, select TDM configuration.
The TDM (E1) Configuration menu appears (see Figure D-17).
3. From the TDM (E1) Configuration menu, configure the following:
Admin 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)
Rx sensitivity (Maximum attenuation of the receive signal that can be
compensated for by the interface receive path):
Short haul (-10 dB)
Long haul (-32 dB)
Line type (E1 framing mode):
Unframed G.703 (Framing is not used)
Framed G.704 (G.704 framing, CRC-4 function disabled)
Framed G.704 CRC4 (G.704 framing, CRC-4 function enabled)
Framed MF (CAS enabled, CRC-4 function disabled)
Framed MF CRC4 (CAS enabled, CRC-4 function enabled).
Idle Code (code transmitted to fill unused timeslots in the E1 frames):
00 to ff.
