Unframed E1, you will be able to use the full bandwidth of the circuit of 2048 kpbs. Normally, for various reasons, this mode is not given to customers by telco.
Costly service
Framed E1 ,you will be able to use 1984Kbps only from 2048Kbps where timeslot 0 is reserved for sync and signaling purposes.
Less costly when compared with Unframed.

What is the definition of Metastable state in laser?
Metastable state in laser is the intermediate state between the e2 and e1 where the excited electron can stay for a comparably long time.
Can the potential difference across a battery be greater than its EMF?
If the emf of a battery is E Volt, the potential difference across a battery is given byV = E -I r where I is the current in the circuit and r is the inetrnal resistance.Hence E and V will be equal only when I = 0.The maximum potential difference across the battery will be equal to E only if I = 0.In gnereral potential difference can be equal or less than the emf.E.m.f can never exceed the potential difference.=====================================A battery charger is a device used to put energy into a secondary cell or (rechargeable) batteryby forcing an electric current through it.Hence to charge a battery another source of emf is needed.The combined emf is now will be (E - E1) where E is the emf of the battey in quesiton and E 1 is the emf of the external source used to charge the battery.Note that E-E1 will be negative in sign.======================================...A battery is charged only when its emf is less than its maximum emf.Suppose that the maximum emf of a cell is 1.5V. The battery should be charged only when its emf is less than 1.5 V say 0.5 V.To charge the cell we use a different source of emf E1 say 3V.The positive of the second source is connected to the negative of the cell so that theCombined emf is now 0.5 - 3 = -2.5V.The negative sign indicates that the emf is opposite to the emf of the cell which is 0.5V.Since the cell is getting charged, the difference in emf is gradually reduced to zero when the cell is fully charged.In modern charging units there are provisions so that the cell is never allowed to be over charged, even if the charging unit is in on for about 12 hours.When the cell is fully charged, (that is when the emf of the cell is now 1.5V), the potential difference between either the second source or cell will be zero.Taking into consideration the sign of the emf and the direction of current through the cell and the sign of the potential difference, the potential difference will be always less than the emf of the cell (which gradually increases while charging).Note that the potential difference is negative if the emf of the cell is taken as positive.Also note that the cell is charged only when its emf is less than its maximum e.m.f
Can two body at same temperature have different heat?
Yes. Heat is energy temperature is not, E1 =k1T and E2 = k2T the temperatures are the same but the heat is different because K1 is different from k2.
How much work must be done on a 1000kg car to increase its speed from 1ms to 2ms?
Initially energy of body will be: E=0.5mv^2 E=0.5*875*44^2 FInnally its energy will be: E=0.5*875*22^2 So loss in energy of body: E2-E1=0.5*875(44^2-22^2) SO this much energy is lost by the body if its speed is reduced to 22m/s. So we will have to do work equivalent to change energy to reduce its Energy. Work=E2-E1 Plz do the calculations
Name three necessary condition for lasing action?
To get laser action 1)population inversion should be achieved to get stimulated emission.(ie)N2>N1 Where N1 and N2 are the number of atoms in level E1 and E2 respectively. 2)stimulated emission should be effective over than the spontaneous emission.

What is the difference between nokia FIU and RRI?
In Technical Terms RRI is a Soft Push and FIU is a hard because when there is an electrical E1 droping we need FIU.
What is the difference between E1 and Ethernet?
Ethernet over E1 converter (also called E1 network bridge) is to transmit Ethernet data over E1 network (PDH,SDH network etc). The Ethernet port connect to terminal device,computer,Ethernet switch,Ethernet router etc. The device's E1 port connect to mail network(PDH SDH etc).E1 over IP (TDMOIP) is to transmit the E1 data over ethernet IPnetwork. It transports the legacy E1 data through the existing Ethernet or IP network. The typical application is transmit voice and data over wireless radio network.

How many E1 lines does PDH has?
There are 63 e1's in sdh STM-1 = 63 x E1; STM-4 = 63 x 4 E1; STM-16 = 63 x 16 E1; STM-64 = 63 x 64 E1.
How do you calculate percentage reduction in expenses?
(E1 - E2)/E1 where E1 is the original expense and E2 is the new, lower expense.
How does E1 interface with basetranceiverstation?
Most likely, the E1 will not interface directly with the base transceiver. The E1 is a 2.048 MHz digitally multiplexed group of 30 E0 (8 KHz voice) channels. The base transceiver requires one or more E0 channels. You need a box in between them ... a multiplex "channel bank", which disassembles the E1 and gives you access to its constituent E0 channels.
How many E1 in STM-0?
STM-0= 21 E1 lines STM-1=(64x1) - 1 = 63 E1 lines STM-4=(64x4) - 4 = 252 E1 lines STM-16=(64x16) - 16 = 1008 E1 lines STM-64=(64x64) - 64 = 4032 E1 lines and so on
What is the paygrade for an E1?
E1 is the paygrade. The rank of an E1 is private, the insignia -- well, there is none, no stripes, no rockers. Are you asking, "What is the pay received by an E1?" If so, the base pay of an E1 is $1347.00 per month. You can look it up here: http://www.militaryfactory.com/military_pay_scale.asp
How many E1 in an SDH radio?
In sdh radio 63 E1's are there
What is an e1 in gsm?
e1 is a standard unit used to measure the amount of data flow. 1 e1 refers to 2mbps speed of data flow.
How many E1 go into a T3?
There is no direct mapping of E1 to DS3. The only way to connect the two is using an MPLS network. A DS3 is 45Mbps. An E1 is 2Mbps. The bandwidth of 22.5 E1's can traverse a DS3. In order to directly connect an E1 as would a T1 to a DS3 you would need an E3 An E3 is 34 Mbps and 16 E1's could connect to it.
