What is E1 and T1

What is E1 and T1

The PDH (plesiochronous Digital Hierarchy) has 2 primary communication systems as its foundation.

These are,
T1 system based on 1544kbit/s that is recommended by ANSI &
E1 system based on 2048kbit/s that is recommended by ITU-T.

Common Characteristics :-

  1. Both are having Same Sampling Frequency i.e. 8kHz.
  2. In both (E1 & T1) Number of samples/telephone signal = 8000/sec.
  3. In both (E1 & T1) Length of PCM Frame = 1/8000s = 125µs.
  4. In both (E1 & T1) Number of Bits in each code word = 8.
  5. In both (E1 & T1) Telephone Channel Bit Rate = 8000/s x 8 Bit = 64 kbit/s.

 

Differing Characteristics :-

  1. In E1 Encoding/Decoding is followed by A-Law while in T1 Encoding/Decoding is followed by µ-Law.
  2. In E1 – 13 Number of Segments in Characteristics while in T1 – 15Number of Segments in Characteristics.
  3. In E1 – 32 Number of Timeslots / PCM Frame while in T1 – 24 Number of Timeslots / PCM Frame.
  4. In E1 – 8 x 32 = 256 number of bits / PCM Frame while in T1 – 8 x 24 + 1* = 193 number of bits / PCM Frame. (* Signifies an additional bit).
  5. In E1 – (125µs x 8)/256 = approx 3.9µs is the length of an 8-bit Timeslot while in T1 – (125µs x 8)/193 = approx 5.2µs is the length of an 8-bit Timeslot.
  6. In E1 – 8000/s x 256 bits = 2048kbit/s is the Bit Rate of Time-Division Multiplexed Signal while in T1 – 8000/s x 193 bits = 1544kbit/s is the Bit Rate of Time-Division Multiplexed Signal.

Basic 3G Performance and Statistic Analysis for Ericcson Equipment

>>> ACCESSIBILITY ANALYSIS:
1. RAN Capacity utilization Analysis and monitoring
›Monitor utilization of RAN capacity to prevent performances degradation due to lack of resources.

›Analyze capacity trend and network growing for upgrade proposal
Capacity Monitored :

CE UL and CE DL utilization
DL power utilization
DL code utilization
HS user utilization
Grace period of license monitoring.
2. Transport and RNC Load Capacity utilization analysis and monitoring
›Monitor utilization of transport capacity to prevent performances degradation due to lack of resources.
›Analyze capacity trend and network growing for upgrade proposal
Capacity Monitored :
Iub (Node to RXI) Utilization
Iub (RXI to RNC) Utilization
Cid Utilization
IuCS Utilization
IuPS Utilization
Iur Utilization
RNC Mpload
3. Audit Node B HW and License Capacity
›Audit actual RBS configuration
›Audit and consistency check RBS parameter
›Monitor actual RBS HW capacity and license capacity
Capacity Monitored :
HW Capacity : RAXB, TXB, RU, E1
License Key Capacity
RBSLocalCell Parameter
NodeBFunction Parameter
RBS Product type
GraceTimePeriod
AAL2 Configuration
IMA Configuration
E1
IubDataStream
AntennaRef
4. Consistency check  RBS and RNC parameter
›Utilize of available resources in RBS
›Utilize of available license in RBS
›Consistency of RBS parameter and RNC parameter
Capacity Monitored:

>>> RETAINABILITY ANALYSIS

1. Drop speech due to soft handover actions

It is dropped Speech calls due to Soft Handover action, which are network initiated call releases due to inability to include a non-valid or valid cell in the active set. This means that missing neighbour drops due to releaseConnOffset exceeding are included. In general every cause that does not allow executing a SHO is triggering the counter at numerator

2. Drop speech due to missing neighbor

It is dropped Speech call due to unknown measured cell (missing neighbor relation).

3. Drop speech due to UL Synchronization lost

It is dropped Speech call due to UL Synchronization Lost. It has to be noted that the counter at numerator is only pegged as a UL synch drop if dchRcLostT (default 5s) expires.

>>> INTEGRITY ANALYSIS

Integrity consist of Soft Handover (SHO) and IRAT Handover performance
