The 1-Port Channelized STM-1/OC-3 Shared Port Adapter data sheet states that it supports:
Up to 84 T1 (or 3 T3) or 63 E1 (or 3 E3) ports
Up to 1022 nxDS-0 channels (where n is 1 to 24) with no T3 configured
Up to 400 nxDS-0 channels (where n is 1 to 24) with one or more T3 configured
Is possible a combination of both: E1 and E3 concurrently?
Data Sheets reports combinations with T1 and T3, but does not include anything regarding E1 and E3.

Hello Albert,
I think you can use a mix of E1 and E3 this is provided by SDH standards
-Port Channelized STM-1/OC-3 SPA Interface Specifications
The framer processes incoming and outgoing SONET or SDH frames. The framer operates at OC-3c/STM-1 line rates (155.52 Mbps).
Packet data is transported with a user-configured encapsulation (such as Point-to-Point Protocol [PPP]) and is mapped into the STS-3c/STM-1 frame.
The 1-Port Channelized STM-1/OC-3 SPA interface is compliant with RFC 1619, PPP over SONET/SDH, and RFC 1662, PPP in HDLC-like Framing. The 1-Port Channelized STM-1/OC-3 SPA also provides support for SNMP v1 agent (RFC 1155-1157), and Management Information Base (MIB) II (RFC 1213).
this is an example taken from cisco IOS XR for GSR but the module is the same:
The following example shows SDH AU-4 configuration.
