AzizGuest Hi, Ive been doing some research on how many E1 circuits can be present in an STM-1 frame. Some websites say 2016, but Ive been trying to do calculations to get this answer and I havent got very far. Is this the correct no. of E1 circuits? 6th April 2003 at 22:26 #35422 Mohd. AzizGuest Just a small update: some websites say 2016 (which is 63 x E1) others say 64, which is 1 x E4. Which one of these is correct? Thanks in advance for any help given… 16th April 2003 at 11:36 #35423 VjGuest 63e1 18th April 2003 at 06:56 #35424 dzoneGuest It’s 63 E1s on the ET-155 (Ericsson AXE interface). 18th April 2003 at 17:11 #35425 SunilGuest DZONE, Are you working in AXE ?
