DS2152

8 SIGNALING OPERATION
The DS2152 contains provisions for both processor based (i.e., software based) signaling bit access and
for hardware-based access. Both the processor-based access and the hardware-based access can be used
simultaneously if necessary. The processor based signaling is covered in Section 8.1 and the hardware
based signaling is covered in Section 8.2.
8.1 Processor-Based Signaling
The robbed-bit signaling bits embedded in the T1 stream can be extracted from the receive stream and
inserted into the transmit stream by the DS2152. There is a set of 12 registers for the receive side (RS1 to
RS12) and 12 registers on the transmit side (TS1 to TS12). The signaling registers are detailed below.
The CCR1.5 bit is used to control the robbed signaling bits as they appear at RSER. If CCR1.5 is set to 0,
then the robbed signaling bits will appear at the RSER pin in their proper position as they are received. If
CCR1.5 is set to 1, the robbed-signaling bit positions are forced to 1 at RSER. If hardware-based
signaling is being used, then CCR1.5 must be set to 0.

Signaling Bit D in Channel 24

RS1.0
Signaling Bit A in Channel 1
Each Receive Signaling Register (RS1 to RS12) reports the incoming robbed-bit signaling from eight
DS0 channels. In the ESF framing mode, there can be up to four signaling bits per channel (A–D). In the
D4 framing mode, there are only two signaling bits per channel (A and B). In the D4 framing mode, the
DS2152 replaces the C and D signaling bit positions with the A and B signaling bits from the previous
multiframe. Hence, whether the DS2152 is operated in either framing mode, the user needs only to
retrieve the signaling bits every 3ms. The bits in the Receive Signaling Registers are updated on
multiframe boundaries so the user can use the Receive Multiframe Interrupt in the Receive Status
Register 2 (SR2.7) to know when to retrieve the signaling bits. The Receive Signaling Registers are
frozen and not updated during a loss of sync condition (SR1.0 = 1). They will contain the most recent
signaling information before the “OOF” occurred. The signaling data reported in RS1 to RS12 is also
available at the RSIG and RSER pins.
