Interface Configuration Guide
3HE 11011 AAAC TQZZA Edition: 01
The 2-port OC3/STM1 Channelized Adapter card has two hot-pluggable, SFP-based
ports that can be configured to be SONET (OC3) or SDH (STM1). All ports on the
2-port OC3/STM1 Channelized Adapter card must be of the same type (either
SONET or SDH).
The 4-port OC3/STM1 / 1-port OC12/STM4 Adapter card has four hot-pluggable,
SFP-based ports that can be configured to be SONET (OC3 or OC12) or SDH (STM1
or STM4). The card can be configured to be in either 4-port mode or 1-port mode
(using the mda-mode command). In 4-port mode, all four ports can be configured as
OC3 or STM1. In 1-port mode, only port 1 can be configured as OC12 or STM4. All
ports on the 4-port OC3/STM1 / 1-port OC12/STM4 Adapter card must be of the
same type (either SONET or SDH).
3.1.3.9 Voice
Voice ports are supported on the following cards:
• 6-port E&M Adapter Card
• 8-port Voice & Teleprotection Card
• 8-port FXO Adapter Card
• 6-port FXS Adapter Card
3.1.3.9.1 6-port E&M Adapter Card
The 6-port E&M Adapter card has six RJ-45 ports that support the transport of an
analog voiceband signal between two analog devices over a digital network. The
analog signals are converted into a 64 kb/s digital Pulse Code Modulation (PCM)
format using either Mu-Law (North America) or A-Law (Rest of World) companding.
The type of companding is selectable on a per-card basis. Companding conversion
(that is, Mu-Law to A-Law or vice versa) is not supported.
The signaling type is selectable on a per-card basis depending on companding type.
When A-Law companding is configured, the signaling type is automatically type V.
When Mu-Law companding is configured, all signaling types can be selected;
however, the only supported configurations are both ends of the connection
operating in the same mode (for example, Type I to Type I) or one end operating in
Type I mode and the other in Type V mode. The default signaling type for Mu-Law is
Type I.
