Installation and Operation Manual Chapter 4 Configuration
IPmux-24 Ver. 1.5 Configuring IPmux-24 for Operation 4-23
³ To configure the external clock E1 interface type:
• From the Physical Layer menu (Configuration > Physical Layer), select External
Clock Interface and choose its type: balanced or unbalanced.
Configuring the T1 TDM Interface
The procedure for configuring the T1 port is similar to the procedure described
above for configuring the E1 port.
³ To configure T1 interface:
1. From the TDM (T1) menu, type F to select one of the T1 links that you intend
to configure.
2. From the TDM (T1) menu, configure the following:
 Administrative Status:
 Up (T1 link is enabled)
 Down (T1 link is disabled)
 Transmit clock source:
 Adaptive (Clock is regenerated from a T1 bundle)
 Loopback (T1 recovered Rx clock is used as the Tx clock)
 Internal (Tx clock is received from an internal oscillator)
 System (System clock is used as the Tx clock)
 Source clock quality (Quality of the adaptive clock used by the device):
 Stratum 1/PRC G.811
 Stratum 2/Type II G.812
 Stratum 3/Type IV G.812
 Stratum 3E/Type III G.812
 Other/Unknown
• The Source Clock Quality parameter is relevant only when the Tx clock source
is set to adaptive or loopback.
• In adaptive clock mode only the Stratum 1/PRC G.811 and Stratum 2/Type II
G.812 values are available when the Ethernet network type is set to LAN.
 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)
 Trail Mode (Enables the end-to-end transfer of TDM OAM (Operation,
administration, and maintenance) data in framed mode, when the
payload format is set to V2.
 Termination (Trail mode is disabled; the TDM networks function as
separate OAM domains)
