A.7.5 Provisioning by NMC (Telnet)
When placed in the CH20 with NMC, this card can be configured through any of the NMC interfaces, including Telnet, Web
GUI and SNMP.
<1> : Port Active - Use this item to enable or disable the line card. When disabled all transmission will be blocked and all
the line card LED indicators will be Off.
<2> : E1/T1 Parameters - This will bring up the sub menu (see below) for setting these specific parameters.
<3> : Timing Source - The timing source can be configured as Internal (Osc), Recover clock from received E1 signal, or
recover clock from signal via fiber. Use the latter setting for the remotely connected fiber unit. Use internal clock for fixed
point to point applications and use E1 recovery when connecting to other E1 networked devices.
<4> : Auto Laser Shutdown (ALS) - Enables or disables the ALS safety feature for the Optical port.
<5> : Active Rates - This item sets the total data nx64k rate for either the E1 (n=1 to 31) or T1 (n=1 to 24).
<6> : Start Timeslot - This unit does not support random timeslot assignment. It supports a contiguous range with a starting
timeslot plus the number of timeslots. This item sets the starting timeslot (default is TS1).
<7> : Loop Back Setting - There is support for loop back of both E1 signal and optical. Refer to the next page.
<8> : Port Reset - This function will clear and reload the CPLD, effectively resetting the port. Data loss will occur when
performing this reset. Use with care.
<9> : Set to Default - This action will return the E1/T1 card to factory default settings.
<D> : Go to Line Card Status menu - If an SFP is installed for optical, the information can be viewed here. See next page.
<N> : Go to the Remote menu - This device supports remote in-band management via Embedded Operations Channel.
E1/T1 Parameter Menu
<1> : E1/T1 Select - Selects the operation mode between E1 or T1.
<2> : Line Code Setting - Selects either AMI line code or HDB3 (for E1) / B8ZS (for T1).
<3> : Full/Fractional - Sets either unframed mode or fractional (nx64k) framing.
<4> : Framer Setting - For E1 fractional, choose between CCS(PCM31) or CAS(PCM30) framing. For T1 select between
D4(SF) or ESF framing.
<5> : CRC Setting - Disables or enable CRC4 for E1 or CRC6 for T1.
<6> : Receive Loss Transmit AIS - When enabled, if a fiber receive experiences LOS then the E1 transmit will issue AIS.
<7> Unused Timeslot Code Setting - Typically the un-used E1 timeslots will have an idle code of 0x7E inserted. This menu
option allows setting the idle code instead to 0xFF.
