Types of Telecom Signaling Card

There are two types of TSC:

V.35 Cards
These are TSCs that communicate using the V.35/V.36 standard (DTE or DCE). The choice of cable determines whether the card uses the DTE or DCE interface type.
These cards have 4 DTE ports or 4 DCE ports, and 4 SS7 links. DTE/DCE can operate at 48.5 (TTC standard only), 56 or 64 kbits/s.
E1/T1 Cards
These are TSCs that communicate using the E1 or T1 standard (standard G.703). The choice of cable determines whether the card uses the E1 or T1 interface type.
These cards have 4 E1 ports or 4 T1 ports, and can support up to 16 SS7 links.




	NOTE: Do not mix card types in a single Telecom Signaling Unit or host server. If you wish to use V.35, E1 and T1 TSCs with your platform, you must install each card type in a separate TSU.
