» CIS (Russian) Signaling Types

»» Types

Stillink systems support the following types of signaling for Russian (and CIS) PSTN:

• Two-bit channel-associated signaling
• Single-bit channel-associated signaling
• Single-frequency (1VF) signaling
• Multifrequency Signaling

E1 trunk types within Stillink systems are local trunks, toll-connecting trunks, and toll-switched trunks for CIS-Russian PSTN. For all such trunk types, both two-bit and single-bit channel-associated signaling types are applicable. For local (SL, CL) and toll-connecting (ZSL, OCL) trunks, available address- and register-signaling options are:

• Pulse
• Multifrequency shuttle (MFC R1.5)
• Multifrequency packet (1, 2, 3a, 3b)

For toll-switched trunks (SLM, TCL), available address- and register-signaling options are:

• Pulse
• Multifrequency packet (3a, 3b)

In addition, line signals can be transmitted/received as voice frequencies. Stillink systems provide 1VF signaling for local, toll-connecting, and toll-switched trunks.
