Register Address (LIUs 1–8):
Bit #

Default
Bits 7 and 6: Jitter Attenuator Bandwidth Selection [1:0] (JABWS[1:0]). In E1 mode, JABWS[1:0] is used to
control the bandwidth of the jitter attenuator according to the following table:
Bit 5: Receive Hitless Protection Mode Control (RHPMC). When this bit is set, the receive impedance match
on/off selection will be controlled by the OE pin. If OE is high, receive impedance match is on. If OE is low, receive
impedance match is off (Internal impedance to RTIP and RRING is high impedance). When this bit is reset, the
RIMPON register bit will control receive impedance match.
Bits 2 to 0: TST Template Select Transceiver [2:0] (TST[2:0]). TST[2:0] is used to select the transceiver that the
Transmit Template Select Register (0x11) will configure for LIUs 1–8. See
