There are 4 types of frames:
Control Frame (CF) always present, named CF-00 Extension Frame (EF) optional, up to 5 (from EF-00 to EF-04)Miscellaneous Frame (MF)General Purpose Frame (GPF)
CF & EF may contain up to 3 shelves

Shelf/card numbering:
they are always composed by 4 chars:
1st number is frame (1=CF-00, 2=EF-00, 3=EF-01...)2nd number is shelf (1=top, 2=middle, 3=bottom)3rd/4th numbers are shelf or card (00=shelf, 01=1st card from left, 02=2nd card from left, etc. - Up to 18 cards)
E.g.: 1203 = CF-00, middle shelf, 3rd board (from left)
Boards xx09 and xx10 are smaller and lay in the same slot, xx09 on top of xx10

It contains the Maintenance & Administration Subsystem (MAS) modules, in fixed slots.
MAS is composed by two MAS Processors (MASP A & B), and one Maintenance Disk & Alarm Card (MDAL).
Each MASP is composed by:
General Purpose Service Module (GPSM-II) card in slot 1113 (forMASP A) and 1115 (for MASP B)
Terminal Disk Module (TDM) in slot 1114 (for MASP A) and 1116 (for MASP BB)
MDAL is a double slot card located in slots 1117 & 1118. It is a single card, not duplicated.
Other slots (except 1109 and 1110) are for application cards

A route is the definition of how to reach a point code via a linkset, with an associated cost
It is possible to configure max. 5000 routes (*)Max number of routes towards a destination is 6 (*)It is possible to associate a cost to each route: if the cost is the same for each route, theres load sharing, otherwise there are preferential routes. In this case, other routes are involved only if theres congestion on preferential routes
