OTUK-SF
Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)
Logical Object: TRUNK
The OTUK-SF condition applies to TXP_MR_10G, TXP_MR_2.5G, TXPP_MR_2.5G, TXP_MR_10E,
TXP_MR_10E_C, TXP_MR_10E_L, MXP_2.5G_10G, MXP_2.5G_10E, ADM-10G, and OTU2_XP cards
when ITU-T G.709 encapsulation is enabled. The condition indicates that incoming signal quality is poor and
that the BER for the incoming line has passed the fail threshold. The BER value is calculated on the Trunk-Rx
port incoming ITU-T G.709 encapsulation frame. If FEC or E-FEC feature is enabled, the BER is a pre-FEC
measurement.
ITU-T G.709 encapsulation refers to a digital data wrapper that is transparent across networking standards
such as SONET and protocols (such as Ethernet or IP).

OTUK-TIM
Default Severity: Critical (CR), Service-Affecting (SA)
Logical Object: TRUNK
The OTUK-TIM alarm applies to TXP_MR_10G, TXP_MR_2.5G, TXPP_MR_2.5G, TXP_MR_10E,
TXP_MR_10E_C, TXP_MR_10E_L, MXP_2.5G_10G, MXP_2.5G_10E, AR_MXP, AR_XP, AR_XPE,
ADM-10G, and OTU2_XP cards when ITU-T G.709 encapsulation is enabled and section trace mode is set
to manual. The alarm indicates that the expected section-monitoring trail trace identifier (TT1) string does
not match the received TTI string and raises a Trace Identifier Mismatch (TIM) alarm. The TIM alarm in turn,
triggers an OTUK-BDI , on page 341 alarm.
